Just wanna know by steps the easyest way to solve this question

X•y=20

x+y=9
y=9-x

x(9-x)=20

9x-x^2=20
-x^2+9x-20 =0

then, you just fact and you can use the same process.
to explain what I just did:
So, it says that the first integer times the second equals 20.
So, x times y = 20
or, x•y=20.

It also says that x plus y is 9. So,
x+y=9. Then, you solve to find one of the integers.
So, if you subtract x from both sides, you get
y=9-x.
Then, since you know what y is, you can plug that in for x•y=20.

Then, you just solve from there. Let me know if you need more help.
