Combine like terms
3x - x = 2x
2x + 15 = 41
Note the equal sign. What you do to one side, you do to the other.
Do the opposite of PEMDAS. Subtract 15 from both sides
2x + 15 (-15) = 41 (-15)
2x = 41 - 15
2x = 26
Isolate the x. Divide 2 from both sides
2x/2 = 26/2
x = 26/2
x = 13
13 is your answer for x
