I would substitute y = x^2
4y^2 -21y+20=0

Answer:
31
Step-by-step explanation:
its just like the area of a sqaure or rectangle
5x6 1/5=
30+1=31
1/5x5/1=5/5=1
6x5=30
3x + y = 9
3x - 5y = 15
15x + 5y = 45
<span>3x - 5y = 15
</span>
18x = 60
x = 10/3 or 3.33.
Plug that into the equation and Y is equal to -1. Hope this helped. Once again the answer is (10/3, -1).
