Question

substitution, 3x-2y=0
2x-y=-1

Answer 1

3x - 2y = 0
2x - y = -1

to make it easier, multiply 2 in the 2nd equation.
3x - 2y = 0
4x - 2y = -2

Subtract both so you can find x
- x = 2
x = -2

substitute x to one of the given equations to find y.
1st eq
3(-2) - 2y = 0
-6 - 2y = 0
-2y = 6
y = -3

2nd eq
2(-2) - y = -1
-y = 3
y = -3


therefore, x = -2 and y = -3

hope this helps! ;)
