Question

find x and y.
help me out​

Answer 1

Answer:

y+x+80=180      - 1

120-x+y=180        -2

add 1  and 2

2y+200=360

2y=160

y=80

sub in 1

80+x+80=180

x=20

Answer 2

Y+X+80=180 (equation 1)

120-X+Y=180 (equation 2)

Adding equation 1 and 2

Y+X+80+120+X-Y=180+180

200+2Y=360

2Y=160

Y=80

Putting value of Y in equation 1

X+Y+80=180

X+80+80=180

X+160=180

X=20
