Answers

x=8/23
i just did it on paper

The solution of the expression will be;

⇒ x = - 8/23

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Now,

Solve the expression as;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Solve for x as;

⇒ - 3.5 + 5.1 = - 4.6x

⇒ 1.6 = - 4.6x

⇒ -4.6x = 1.6

⇒ x = 1.6 / - 4.6

⇒ x = - 16/46

⇒ x = - 8/23

Thus, The solution of the expression will be;

⇒ x = - 8/23

The answer is 14 because -2 x -7 = 14. If you didn’t already know a sum is the value given when two or more numbers are multiplied together and the reason -2 and -7 multiply to get 14 is because the negatives cancel each other out to create a positive.

it’s just -9 since 2 + 7 is 9, but they’re opposite signs so it’ll be (-2) + (-7) = -9. The signs don’t change since both numbers are negative
