You could use substitution or elimination... do you prefer one or the other?

Doesn't matter :)

From the first equation, a = 150 - s (subtracting 150 from both sides)
Now, substitute a = 150 - s into the second equation, so you have 45(150 - s) + 28.50 s = 4770
6750 - 45s + 28.50 s = 4770
6750 - 16.5s = 4770
-16.5s = -1980
s = 120.

We know s = 120; to find a, substitute s = 120 into the first equation,

a + s = 150
120 + s = 150
s = 30

Therefore, the final answer is a = 120 and s = 30.

k then, elimination is easy enough... multiply the first equation by 45:

45a+45s=45*150
$45.00a+$28.50s=$4770

now subtract the 2nd equation from the first.
