Answer:
x= 23
y=7
Step-by-step explanation:
x-y=16
4y-5=x
4y-5-y=16
3y-5=16 add 5 to both sides
3y=21 divide by 3 on both sides
y=7
x-7=16 substitute back in
x=23 added 7 to both sides
so x=23 and y=7
23-7=16
Answer:
- 439
Step-by-step explanation:
evaluate f(- 7) and substitute the value obtained into s(x)
f(- 7) = 3(- 7) = - 21 , then
s(- 21) = 2 - (- 21)² = 2 - 441 = - 439
