Answer:

x = 6 and y = 2

Step-by-step explanation:

2x + 3y = 18 .......... Eqn 1

3x - 3y = 12 ........... Eqn 2

Add both Equations to eliminate y

we have

2x + 3x + 3y - 3y = 18 + 12

5x = 30

Divide both sides by 5

5x / 5 = 30/5

x = 6

Substitute x = 6 into any of the Equations

Using equation 1

we have

2(6) + 3y = 18

3y = 18 - 12

3y = 6

Divide both sides by 3

That's

3y/3 = 6/3

y = 2

Therefore x = 6 and y = 2

Hope this helps
