So you make your equation 4x+20+40=180. Add like terms and get 4x+60=180. Subtract 60 from both sides, get 4x=120. Divide boths sides by 4, get your answer of x=30. Hope this helps
30. A straight line is 180 Take 40 = 140 Take 20 = 120 Divide by 4 = 30 4x+20+ 40 = 180 Rearrange to find x X= 180-60 all divided by 4 X= 120/4 X= 30
