4x+3y=19 and 6x-5y=-57
eliminate
multiply first equation by -6 and 2nd by 4
and add them
-24x-18y=-114
<u>24x-20y=-228 +</u>
0x-38y=-342
-38y=-342
divide both sides by -38
y=9
sub back
4x+3y=19
4x+3(9)=19
4x+27=19
minus 27 both sides
4x=-8
divide 4
x=-2
(x,y)
(-2,9)

Step-by-step explanation:
Since Maya's new home had a purchase price of $ 325,500, and Maya and her husband got a 15-year fixed mortgage for 70% of the purchase price, and the interest rate on the loan was 2,990%, to determine what was their monthly payment, the following calculation must be performed:
((325,500 x 0.7) x 1.0299) / (12 x 15) = X
(227,850 x 1.0299) / 180 = X
234,662,715 / 180 = X
1,303.68 = X
Therefore, their monthly payment will be $ 1,303.68.
