First combine like terms
2x + 3x = 5x
5x + 50 = 180
since there is an equal sign, what you do to the one side, you do to the other
Isolate the x
Subtract 50 from both sides
5x + 50 = 180
5x + 50 (-50) = 180 (-50)
5x = 180 - 50
5x = 130
Divide 5 from both sides to isolate x
5x/5 = 130/5
x = 130/5
x = 26
x = 26 is your answer
hope this helps
