Question

Solve for x: 3x + 2 = 7x - 6

Answer 1

Answer:

$\sf D.\;\;x=2$

Step-by-step explanation:

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

Subtract 2 from both sides:-

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

Simplify:-

$\sf 3x=7x-8$

Subtract 7x from both sides:-

$\sf 3x-7x=7x-8-7x$

Simplify:-

$\sf -4x=-8$

Divide both sides by -4:-

$\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}$

Simplify:-

$\sf x=2$

Answer 2

Answer: D.2

Work:
8=4x
x= 2
