Question

5x + 3 = 2x + 15

Answer 3

12

Answer 4

You want to get the x alone.
Get all the x-es on one side and the numbers on the other side
Then divide by the coefficient on x.

Example:

2x-1=3x+3
2x-3x=3+1
-x = 4
x = 4

Try to do that with your problem.

Answer 5

\[\huge{5x+3=2x+15}\]
\[\huge{5x+3-2x=15}\]
\[\huge{3x+3=15}\]
\[\huge{3x=15-3}\]
\[\huge{3x=12}\]
\[\huge{x=\frac{12}{3}=4}\]
