Answer:
Step-by-step explanation:
I have the same question and I'm looking for the answer
-7x+y=42
y=42+7x
5x+13y=66
Substitute for y (meaning put 42+7x into the equation above instead of y because they are equal - see second line of my answer above)
5x+13[42+7x] = 66
5x +546 = 66
5x=66-546
5x=-480
x=-480/5
x=-96
Answer:
f(x)=9x-7
when x=-1
f(-1)=9×-1-7=-9-7=-16
when x=0
f(0)=9×0-7=-7
