solve for x 3(-x-3)+x-3=26

Answers

Answer:

[tex]\boxed {x = -19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]3(-x - 3) + x - 3 = 26[/tex]

-Use Distributive Property:

[tex]3(-x - 3) + x - 3 = 26[/tex]

[tex]3(-x ) - 9 + x - 3 = 26[/tex]

-Combine both [tex]-9[/tex] and [tex]3[/tex]:

[tex]3(-x ) - 9 + x - 3 = 26[/tex]

[tex]3(-x ) - 12 + x = 26[/tex]

-Add [tex]12[/tex] to both sides:

[tex]3(-x ) - 12 + 12 + x = 26 + 12[/tex]

[tex]3(-x) + x = 38[/tex]

-Multiply the [tex]-1[/tex] by [tex]3[/tex]:

[tex]3(-x) + x = 38[/tex]

[tex]-3x + x = 38[/tex]

-Combine both the [tex]-3x[/tex] and [tex]x[/tex]:

[tex]-3x + x = 38[/tex]

[tex]-2x = 38[/tex]

-Divide both sides by [tex]-2[/tex]:

[tex]\frac{-2x}{-2} = \frac{38}{-2}[/tex]

[tex]\boxed {x = -19}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-19[/tex].

 [tex]\bold{Hello!}\\\bold{Your~Answer~Is~Below!}[/tex]

______________________________

 [tex]\bold{Solution~Steps:}[/tex]

When we have a problem with parenthesis we must use distributive property:

[tex]3[/tex] × [tex]-x-3[/tex]The [tex]3[/tex] cancels out, leaving [tex]-x[/tex]

         * [tex]3(-x)-9+x-3=26[/tex]

Subtract [tex]3[/tex] from [tex]-9[/tex]:

[tex]3-(-9)=-12[/tex]

         * [tex]3(-x)-12+x=26[/tex]

Add [tex]12[/tex] to both sides:

Since [tex]-12[/tex] is negative we do the opposite of what we see, so it cancels out.  [tex]-12+12=[/tex] Cancels out[tex]26+12=38[/tex]

         * [tex]3(-x)+x=38[/tex]

Multiply [tex]3[/tex] and [tex]-1[/tex]:

In this case we have [tex]2[/tex] x's, so we need to get rid of one. We do this by turning [tex](-x)[/tex] into [tex]-1[/tex]. Then we multiply them together: [tex]3[/tex] × [tex]-1=-3[/tex]

         * [tex]-3x+x=38[/tex]

Combine like terms:

[tex]-3x+x=-2x[/tex]

         * [tex]-2x=38[/tex]

Divide to get [tex]x[/tex] alone:

Divide by [tex]-2[/tex] on each side by rule of opposites: [tex]-2x[/tex] ÷ [tex]-2=x[/tex] [tex]38[/tex] ÷ [tex]-2=-19[/tex]

        [tex]\boxed{x=-19}[/tex]

*HELP ME PLEASE* Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.

Give a value of n so that the equation has no solutions.

Explain why you are correct.

Answers

Answer:

n  = -14

Step-by-step explanation:

Let us try to solve this equation for n;

     3x + 1 - 9  = 3(x + 2)  + n

     3x  - 8  = 3x + 6 + n

      3x - 3x -8 - 6  = n

              -14  = n

The value of n  = -14

This value is the value of the equation that will have no solution.

 To know if we are correct, let us input this value into the expression

        3x + 1 - 9  = 3(x + 2)  + n

        3x - 8  = 3x + 6 -14

 Collect like terms;

        3x - 3x  = 8 + 6 - 14

               0 = 0

A shipping company charges a $6.50 flat fee for a package, plus a fee based on the weight of the package. The
company charges $1.50 per pound, plus an additional $0.25 for every pound over 6 pounds.
Samuel plans on sending a package that is over 6 pounds. He has $26 to spend on shipping. What is the
maximum number of pounds that this package could be?
1. The cost of shipping 6 pounds is
2. The Maximum number of pounds is

Answers

Answer:  The cost of shipping 6 pounds is $ 9.00

The maximum number of pounds he can ship is 74 pounds.

Step-by-step explanation:

To find the cost for the first 6 pounds, multiply $1.50 × 6 = $9.00

To find out how much more he can ship, subtract: $26 - $9 = $17

The number of pounds that can be shipped for $0.25 is 17 divided by .25

17/.25 = 68

The total maximum weight  is 6 + 68 = 74 pounds.

Check: 6 pounds for $ 9.00 plus 68 pounds for $17.00

The money adds up to $26 and the weight adds up to 74 pounds.
