Steve
x + 3y = 32
-3x + 2y = 3
Add 3x1st to 2nd to produce
11y = 99
y = 9
so,
x = 5
___________
x + y = 6
x - y = -9
add the two equations to get
2x = -3
x = -3/2
so,
y = 15/2
-3x + 2y = 3
Add 3x1st to 2nd to produce
11y = 99
y = 9
so,
x = 5
___________
x + y = 6
x - y = -9
add the two equations to get
2x = -3
x = -3/2
so,
y = 15/2
