Answer: =−20
y=2
Step-by-step explanation:
Solve for xx in -5y-10=x−5y−10=x.
x=-5y-10
x=−5y−10
2 Substitute x=-5y-10x=−5y−10 into x+9y=-2x+9y=−2.
4y-10=-2
4y−10=−2
3 Solve for yy in 4y-10=-24y−10=−2.
y=2
y=2
4 Substitute y=2y=2 into x=-5y-10x=−5y−10.
x=-20
x=−20
5 Therefore,
\begin{aligned}&x=-20\\&y=2\end{aligned}
x=−20
y=2
Answer:
y = 51
x = 129
z = 129
Step-by-step explanation:
y and 51 are vertically opposite angles, and therefore are equal.
51 x 2 = 102
360 - 102 = 258
258 / 2 = 129
x and z are also vertically opposite, and therefore equal.
