Question 30590: Solve the system of equations using the substitution method.
3x + y = 2
2x – y = 3
This is what I cam up with, but It doesn't seem correct.
3x + y =2
Isolate the y by sub. 3x from both sides
3x-3x + y =3x +2
substitute 3x + 2 for y
2x - 3x + 2=3
This is where I get lost, not sure if this is even correct
