Question

What is the answer for x, if 3x+7=13

Answer 1

3x+7=13.
3x=13-7
3x=6
At this point you would divide the 3 and 6 and you would get 2

The answer is 2.

Answer 2

3x+7=13

move +7 to the other side

sign changes from +7 to -7

3x+7-7= 13-7

3x= 6

divide by 3 for both sides

3x/3= 6/3

x=2

Answer : x= 2
