x=12

Explanation:

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

Explanation:

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!
