#x=12#

Given: #5x+20=80#

Subtract #20# from both sides.

#5x+color(red)cancelcolor(black)20-color(red)cancelcolor(black)20=80-20#

#5x=60#

Divide by #5#.

#(color(red)cancelcolor(black)5x)/(color(red)cancelcolor(black)5)=60/5#

#x=12#

#x=12#

Recall that we want to isolate the #x# term. We can start to do this by subtracting #20# from both sides to get

#5x=60#

Our last step would be to divide both sides by #5#. We get

#x=12#

Hope this helps!
