Answer:

  • x = 11
  • y = 4

Step-by-step explanation:

In order to solve this, we need to assume that the angles involving x are supplementary, and the angles involving y are complementary.

  (7x -8) +(13x -32) = 180

  20x -40 = 180 . . . . . . . . . collect terms

  20x = 220 . . . . . . . . . add 40

  x = 11 . . . . . . . . . . divide by 20

__

  (10y +22) +(7y) = 90

  17y = 68 . . . . . . . . . . . . collect terms, subtract 22

  y = 4 . . . . . . . . . . divide by 17

Let's solve this inequality:-

3x<18

Divide both sides by 3:-

x<6

So numbers less than 6 will make this inequality \sf{true}.
