Answer:
y = 16x + 4
y = 25x - 23
____________
16x + 4 = 25x - 23
27 = 9x
3=x
__________
y = 25(3) - 23
y = 75 - 23
y = 52
_________
They will intersect at (3, 52)
Step-by-step explanation:
The second step which is bolded I simplified the equation. In the next step I'm going to substitute 3 into the second equation.
9/19 = x / 152....9 oz oil to 19 gallons gas = x oz oil to 152 gallons gas
cross multiply because this is a proportion
(19)(x) = (152)(9)
19x = 1368
x = 1368/19
x = 72 oz of oil <==
