Answer:

  1. x = 36
  2. x = 80
  3. x = 137            y = 43
  4. x = 10             y = 20

Step-by-step explanation:

  1. 180-144 = 36
  2. 360 = 85+35+3x = 120+3x = [tex]\frac{360-120}{3}[/tex] = x = 80
  3. a) 90-47 = y = 43                         b) 180-y = x = 180 - 43 = 137
  4. 5x+45+(-5x-5)=y+2x-5 (-5x-5) = 40= y+2x
