Answer:

x = 8

z = 74

Step-by-step explanation:

opposite angles are equal

10x + 26 = 8x + 42

combine similar terms:

10x - 8x = 42 - 26

simplify:

2x = 16

x = 16/2

x = 8

<u>solve for z:</u>

360 = 10x + 26 + 8x + 42 + z + z

360 = 10(8) + 26 + 8(8) + 42 + 2z

360 - 80 - 26 - 64 - 42 = 2z

148 = 2z

z = 148/2

z = 74

jeka57 [31]

Answer:

m=31/2, n=-24. (31/2, -24).

Step-by-step explanation:

2m+n=7

4m+3n=-10

4m+3(7-2m)=-10

4m+21-6m=-10

-2m=-10-21

-2m=-31

2m=31

m=31/2

2(31/2)+n=7

31+n=7

n=7-31

n=-24
