The two numbers that add up to get -1 and multiply to get -20 are -5 and 4
-5*4=-20
-5+4=-1
I hope this helps
Julie : 5.62
Micah : 5.62 x 5 = 28.1
Jermy : 5.62 + 6.72 = 12.34
Change first equation
x - 2y = 1
add 2y to both side
x = 2y + 1
Plug into second equation
3(2y+1) - 6y = 3
Distributive property
6y + 3 - 6y = 3
y = 0, plug into first equation
x - 2(0) = 1, x = 1
Solution: x = 1, y = 0
