Answer: D.2

Work:
8=4x
x= 2

Answer:

[tex]\sf D.\;\;x=2[/tex]

Step-by-step explanation:

[tex]\sf 3x + 2 = 7x - 6[/tex]

Subtract 2 from both sides:-

[tex]\sf 3x+2-2=7x-6-2[/tex]

Simplify:-

[tex]\sf 3x=7x-8[/tex]

Subtract 7x from both sides:-

[tex]\sf 3x-7x=7x-8-7x[/tex]

Simplify:-

[tex]\sf -4x=-8[/tex]

Divide both sides by -4:-

[tex]\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}[/tex]

Simplify:-

[tex]\sf x=2[/tex]
