Answer:

x=20

y=67

Step-by-step explanation:

making two equations,

5x +13+y=180( angles on a line)

subjecting y,

y=167-5x

another equation,

y+4x+2+2x-9=180( sum of angles in a triangle)

substitute the first equation and simplify,

167-5x+6x=187

x=20

using this in the first equation you will get y=67
