Answers

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

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
