Answer:
Answers for 19, 20, 22, 24, and 25.
Step-by-step explanation:
19. 23x - 16 + 8x - 21 = 180
x = 7
23 (7) - 16 = 7y - 23
y = 24
20. 10x -17 = 8x + 1
x = 9
6y + 29 + 73 = 180
y = 13
22. 8x - 35 + 6x - 5 + 3x - 1 = 180
x = 13
24. m<R is 74
m<Q is 32
25. m<E is 37
m<G is 37
I didn't know the answers for all, but I hope this helps in some way!
Let z be any number (like x would be)
if we set z equal to 2x-6y, then we get z = 2x-6y
The system
2x-6y = 8
2x-6 = 3
turns into this new system
z = 8
z = 3
but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
