Answer:
x = 15; y = 8; m<Q = 83
Step-by-step explanation:
2x + 7 = x + 22
x + 7 = 22
x = 15
8y - 4 = 4y + 28
4y - 4 = 28
4y = 32
y = 8
2x + 7 + 8y - 4 + m<Q = 180
2(15) + 7 + 8(8) - 4 + m<Q = 180
30 + 7 + 64 - 4 + m<Q = 180
m<Q + 97 = 180
m<Q = 83
Answer:
7/3x + 2/3 = 7/9x - 5/6
7/3x - 7/3x + 2/3 = 7/9x - 7/3x - 5/6 (7/9x-7/3x--->7/9x-21/9x---> -14/9x)
2/3= -14/9x - 5/6
2/3+5/6 = -14/9x - 5/6 + 5/6 - (2/3 + 5/6---> 4/6 + 5/6---> 9/6 ----> 3/2)
3/2 = -14/9x
3/2 / -14/9 = -14/9x / -14/9 - (3/2 / -14/9 ------> 3/2 x -9/14 ----->
- 27/28)
-27/28 = x
