Question

-8x + 14 = -2(4x - 7) what is the value of x

Answer 1

Explanation:

-8x + 14 = -2(4x - 7)

use the distributive property to get rid of the parentheses (-2 x 4x and -2 x -7) (negative times negative equals positive)

-8x + 14 = -4x + 14

subtract 14 on both sides to cancel out 14

-8x is not equal to -4x

although this may seem like a weird answer, if x is the same variable (pretend it's one) 1 multiplied with -8 will not equal 1 multiplied with -4

Answer 2

all real numbers

Explanation:

Given

- 8x + 14 = - 2(4x - 7) ← distribute parenthesis

- 8x + 14 = - 8x + 14

Since both sides are equal, then any real value of x is a solution of the equation.
