Answer:
x=3
Step-by-step explanation:
distribute 3 into (x+2)
3x+6=x+12
move all the x variables to one side and all the numbers to another side
3x+6=x+12 -3x -3x
6=-2x+12
-12 -12
6-12=-2x
-6=-2x
isolate x by dividing everything by -2
-6/-2=-2x/-2
eliminate the -2 multiplying the x with the -2 dividing the -2x
-6/-2= x
x=3
