solve 27x – 2 = 3x + 10

27x-2=3x+10

add 2 to both sides to isolate the 27 x

27x-2+2=3x+10+2

you will end up with

27x=3x+12

The next step is to subtract 3x from both sides

27x-3x=3x+12-3x

you will end up with 

24x=12

finally divide both sides by 24

24x/24=12/24

you will get

x=12/24 or reducing x=1/2

x = 0.5 or 12/24
