( WILL GIVE BRAINLEST)

x=4-y

x=4−y

Step-by-step explanation:

1 Factor out the common term 22.

-2(x+y)=-8

−2(x+y)=−8

2 Divide both sides by -2−2.

x+y=\frac{-8}{-2}

x+y=

−2

−8

​

3 Two negatives make a positive.

x+y=\frac{8}{2}

x+y=

2

8

​

4 Simplify  \frac{8}{2}

2

8

​

  to  44.

x+y=4

x+y=4

5 Subtract yy from both sides.

x=4-y

x=4−y

Done

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
