Answer:

x = - 3

y = - 2

Step-by-step explanation:

Start with the second equation. Switch

3y = 2x Divide by 3

3y/3 = 2x/3

y = 2x/3

Now go to the first equation. Put the value for y in the first equation.

x - 3(2x/3) = 3 Cancel the 3s on the left.

x - 2x = 3 Combine

-x = 3 Multiply by -1

-1(-x) = 3(-1)

x = - 3

Now go back to the original equation I have called the second equation

2x = 3y

2(-3) = 3y Put in - 3 for x

- 6 = 3y Divide by 3

-6 / 3 = y

y = - 2
