To solve we multiply the last equation by 5 and we get the following:
5x-5y=90
But 5x=3y and we replace it in this equation:
3y-5y=90
-2y=90
y=-45
and x-(-45)=18 , x+45=18
x=-27

Hello
if m s : sum and p : <span> product
the </span><span> quadratic equation is : x²-sx+p=0
s = 5 p=-24
x²-5x-24 = 0 </span>
<span>12a^3b + 8a^2b^2 − 20ab^3
</span>12a^3b = 4ab(3a^2)
8a^2b^2 = 4ab(2ab)
20ab^3 = 4ab(5b^2)
GCF = 4ab
12a3b + 8a2b2 − 20ab3 = 4ab(3a^2 + 2ab - 5b^2)
