Answer:

333

283

Step-by-step explanation:

1 Solve for yy in 13+2x+y+90=18013+2x+y+90=180.

y=-2x+77y=−2x+77

2 Substitute y=-2x+77y=−2x+77 into 4x+1+8x-2y=1804x+1+8x−2y=180.

16x-153=18016x−153=180

3 Solve for xx in 16x-153=18016x−153=180.

x=\frac{333}{16}x=

333

4 Substitute x=\frac{333}{16}x=

333

into y=-2x+77y=−2x+77.

y=\frac{283}{8}y=

283

5 Therefore,

\begin{aligned}&x=\frac{333}{16}\\&y=\frac{283}{8}\end{aligned}
