Question

1. 4x + 2x + 2 = 3x - 7

Explanation:

Step1: Combine like terms on left

$6x + 2 = 3x - 7$

Step2: Subtract $3x$ from both sides

$6x - 3x + 2 = -7$
$3x + 2 = -7$

Step3: Subtract 2 from both sides

$3x = -7 - 2$
$3x = -9$

Step4: Divide by 3 on both sides

$x = \frac{-9}{3}$

Answer:

$x = -3$
