Question

Which values of x and y will satisfy y = 5x and 12x + 9y = 60?

Answer 1

y = 5x
12x + 9y = 60

Use substitution and solve the system
12x + 9(5x) = 60
12x + 45x = 60
57x = 60
x=20/19

y = 5(20/19)
y= 100/19
i got the answer from here http://openstudy.com/study#/updates/5255709de4b037f05886f028

Answer 2

check\[y=5x\]\[\frac{100}{19}=5(\frac{20}{19})\]\[\frac{100}{19}=\frac{100}{19}\]looks good @doggy
