Solve the equation 3(x+2)=x+12 provide a justification for each step

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
Answer:
x=3
Step-by-step explanation:
3(x+2)=x+12
First, distribute the 3(x+2).
3x+6=x+12
Next, subtract 1x from each side. That will cancel out the x in the x+12.
2x+6=12
Subtract 6 from both sides. Canceling out the 6 in the 3x+6.
2x=6
Divide both sides by 2.
x=3
