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]
