6(2x-5)=4x+2
| first you multiply out the bracket on the left side, so 6 x 2x = 12x and then 6 x -5 = -30
12x-30=4x+2
| Next you get all of the x terms onto one side, so take -4x from both sides
8x-30= 2
| Get all of the other terms onto one side, so add 30 to both sides
8x= 32
| Then you solve it by dividing both sides by 8
x= 4
