First multipy the left side of the equation:
6x - 8 = 3x + 7

Subtract 3x from both sides:
6x - 8 - 3x = 3x - 3x + 7

Put the x together of both sides:
(6x - 3x) - 8 = (3x-3x) + 7

Resulting in:
3x - 8 = 7

Add 8 to both sides of the equation:

3x - (8 + 8) = 7 + 8

3x = 15

Divide both sides by 3:

3x/3 = 15/3

Answer: x = 5

I hope this is clear enough for you.

multiply 2*3x and 2*4 to get 6x-8=3x+7
then you subtract 3x from both side to get 3x-8=7
then add 8 to both sides 3x=8+7, 3x=15
divide both sides by 5, x=5
