Question

match each equation with an equivalent equation. some of the answer choices are not used.3 x + 6 = 4 x + 7 3 (x + 6) = 4x+7 4 x + 3 x = 7 - 6answer choices:7x=13x-1=4x9x=4x+73x=4x+73x+18=4x+7

Answer 1

We will start by solving each equation;

3 x + 6 = 4 x + 7

subtract 7 from both-side of the equation

3x + 6-7 = 4x + 7 -7

3x - 1 = 4x

3 (x + 6) = 4x+7

open the parenthesis

3x + 18 = 4x + 7
