Note: Your equation seems a little unclear. But, I am assuming that your equation is:

[tex]e^x\:+\:e^{-1}=\:2[/tex]

Because my solution would still clear your concept about this topic, no matter what the question is.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex]e^x\:+\:e^{-1}=\:2[/tex]

subtract [tex]e^{-1}[/tex] from both sides

[tex]e^x+e^{-1}-e^{-1}=2-e^{-1}[/tex]

[tex]e^x=2-\frac{1}{e}[/tex]

[tex]\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)[/tex]

[tex]\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)[/tex]

[tex]\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)[/tex] ∵ [tex]\:\:\ln \left(e\right)=1[/tex]

[tex]x=\ln \:\left(2-\frac{1}{e}\right)[/tex]

help

Answers

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

[tex]3x - 5 = 10[/tex]

We want to isolate the x.

[tex]3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5[/tex]

[tex]3x = 15[/tex]

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

[tex]\frac{3x}{3} \;=\;\frac{15}{3}[/tex]

[tex]x = 5[/tex]

At a charity fund raiser, adult tickets were sold for $11 each and children’s tickets were sold for $5 each. Write an algebraic expression for the total amount of money raised from the sale of tickets. How much money was raised if the fund raiser sold 247 adult tickets and 390 children’s tickets? Let a= number of adult tickets and c= number of child tickets.

Answers

9514 1404 393

Answer:

11a +5c$4667

Step-by-step explanation:

If 'a' adult tickets are sold for $11 each, the amount of money they sold for is ...

11a

If 'c' children's tickets are sold for $5 each, the amount of money they sold for is ...

Then the expression for the total amount from the sale of tickets is ...

11a +5c . . . . total of money raised

The value of this expression for a=247 and c=390 is ...

11·247 +5·390 = 2717 +1950 = 4667

A total of $4667 was raised by the sale of tickets.

Answer:

x = 9

Step-by-step explanation:

First equation = 4x - 8

Second equation = 7x - 35

Seperate the equation with an equal sign to make it an equality equation and solve for X so :

4x - 8 = 7x - 35 (Given)

-3x - 8 = -35 (Subtraction property of equality)

-3x = -27 (Addition property of equality)

x = 9 (Division property of equality)

Solution:

x = 9
