Answer:

x=41

y=139

Step-by-step explanation:

x+y = 180 since they form a straight line

y is 3x +16

y = 3x +16

Replace y in the first equation

x+3x +16 = 180

Combine like terms

4x +16 = 180

Subtract 16 from each side

4x+16-16 =180-16

4x =164

Divide each side by 4

4x/4 =164/4

x = 41

y = 3x +16

y = 3*41 +16 = 123+16 =139
