Answer:
x = 0
Step-by-step explanation:
It seems to me this just wants you to add the 3 equations.
2m + 2n +5p
Y = 44
180 - 88 = 92
180 - 92 = 88
88/2 = 44
The answer is 4565 / 63
Sorry this might be to late...
Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13
