Answer:
x = 2
As x = 12/6 = 2
Step-by-step explanation:
3x-4+3x-8
3x+3x-4-8
= 6x-12
FACTORISING for check and set to zero
6(x-2)
6x -12 = 0
Cancel out left by adding 12 to both sides then applying /6 to both sides to cancel 6 left side.
6x--12 + 12 = 0 + 12
6x / 6 = 12 / 6
x = 12/6
x = 2
or balance as grouping by separation = multiply at end by -1
3x+3x = --4 - 8
6x = - 12
x = - 12/6
x = - 2
x = - 2 ( -1 )
x = 2
