Ok first you must simplify the parentheses following the rules of PEMDAS and go from there

Add 12 to both sides

8(3x - 4) = 4 + 12

Simplify 4 + 12 to 16

8(3x - 4) = 16

Divide both sides by 8

3x - 4 = 16/8

Simplify 16/8 to 2

3x - 4 = 2

Add 4 to both sides

3x = 2 + 4

Simplify 2 + 4 to 6

3x = 6

Divide both sides by 3

x = 6/3

Simplify 6/3 to 2

x = 2
