Question

60x+30y=2400+h
40x+35y=1750
35y=1470


solve for x and y

thank you....please show steps

Answer 1

still got that pesky +h in there?
multiply #1 by 2 and #2 by 3
120x + 60y = 4800
120x + 105y = 5250
now subtract to get
45y = 450
y = 10
use that to get x

No idea where the 35y=1470 came from.
