Can someone help me please ASAP

A. x = -3, 6

Step-by-step explanation:

the equations are xy = 6 and 3y = x - 3

we need to find x so we can separate it from y by changing any equation.

we going to change xy = 6 to y = 6 / x

now the equations are:

y = 6 / x

3y = x -3

we can substitute y into the second equation now.

3(6/x) = x - 3

18 / x = x - 3

18 = x (x-3)

18 = x^2 - 3x

x^2 - 3x - 18

(x - 6)(x + 3) = 0

x - 6 = 0

x = 6

x + 3 = 0

x = -3
