Question

7. What is the value of X in the equation shown?
-15 = 2X + 5

Answer 1

To find the value of X in the equation -15 = 2X + 5, we can solve for X by isolating the variable on one side of the equation.

Given: -15 = 2X + 5

Subtracting 5 from both sides of the equation:

-15 - 5 = 2X + 5 - 5

-20 = 2X

To isolate X, we need to divide both sides of the equation by 2:

-20 / 2 = 2X / 2

-10 = X

Therefore, the value of X in the equation -15 = 2X + 5 is -10.

Answer 2

-10

Explanation:

-15 = 2x +5

move the numbers to one side

-15 + (-5) = 2x

-20 = 2x

devide by 2 to only be left with x

x = -10
