6A + 4S = 548
s = 12 + A

Substitute
6A + 4(12 + A) = 548
6A + 48 + 4A = 548
10A = 500
A = 50
S = 62

Answer:

I think number 1=209

number 2=120

number 3=89

Step-by-step explanation:

x= 1st aircraft

y=2nd aircraft

z=3rd aircraft

x=y+89

y=z+31

z=y-31

x+y+z=418

y+89+z+31+y-31=418

2y+89+z=418

2y+z=329

2y+(add z)

2y+y-31=329

3y=360

y=120

x=120+89=209

z=120-31=89

K= -9

Well, h(x) and g(x) both of x^2, so we can disregard that part.
h(x) has +3 and g(x) has -6.
3 - 9 = -6. (Which makes them equal)

g(x) = h(x) + (-9)
x^ - 6 = x^ + 3 - 9
x^ - 6 = x^ - 6
