Hi Mr Hanneson,
I used the elimination method
I got the solution:- y = 2.8 and x = -0.2
Did I do it right?
I multiplied the first equation by 2 and the second equation by 3. then I eliminated 6x from both sides by subtracting 2nd eqn from the 1st on. then I got those above values.
Your calculations are perfect

How did a subtraction of y
We started with:
We started with:
QUANTITY A: x
QUANTITY B: y
If we subtract y from both quantities, we get:
QUANTITY A: x - y
QUANTITY B: y - y
Simplify to get:
QUANTITY A: x - y
QUANTITY B: 0
