Question

If x² - y² = 24, and x - y = 6, then y =

Answer 1

hint:
(x-y)*(x+y)=x^2-y^2

Answer 2

\[x^2-y^2=(x-y)*(x+y)\]

Answer 3

Exactly what I was going to say^^ lol

Answer 4

so we have:
6*(x+y)=24



x+y=4
x-y=6

can you solve this system?

Answer 5

i got -1

Answer 6

4-x=x-6
-2x=-2
x=-1

so x is -1 yeah,

now substitute -1 for x and solve for y
