i can't believe that such a simple problem made it to 11th grade homework! Anyway, here's the answer:
6x + 4(3x – 2) = 6x + 2
6x + 12x - 8 = 6x + 2
18x - 8 = 6x + 2
18x - 6x = 2 + 8
12x = 10
x = 10/12
= 5/6
Check the solution:
Put x = 5/6
6(5/6) + 4[3(5/6) - 2] = 6(5/6) + 2
5 + 4(5/2 - 2) = 5+2
5 + 4(1/2) = 5+2
5+2 = 5+2
7 = 7
LHS = RHS
Therefore, the solution is correct
P.S : I'm a seventh grader

Distribute the 4 to cancel out parenthesis
6x + 12x - 8 = 6x + 2
Combine like terms
18x - 8 = 6x + 2
Get x by itself
12x = 10
Solve for x and simplify
x = 10/12 = 5/6

6x + 4(3x – 2) = 6x + 2
6x+12x-8=6x+2 subtract 6x & add 8 to each side
12x=10
x=5/6
check
6(5/6)+4(3*5/6-2=6(5/6)+2
5+4(5/2-2)=5+2
5+10-8=7
15-8=7

Distribute:
6x + 12x - 8 = 6x + 2
Rearrange and combine like terms:
6x - 6x + 12x = 2 - (-8)
so
12x = 10
therefore
x = 10/12 = 5/6

6x + 4(3x - 2) = 6x+2
6x + 12x - 8 = 6x+2
18x - 8 = 6x+2 (add 8 to both sides)
18x = 6x+10 (subtract 6x from both sides)
12x = 10 (divide both sides by 12)
x = 10/12
x = 5/6
