2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
y=16 x= -4
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
No.

No.
Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!
x = 2.15 and y = 3.75
2x+3y=13 3x-y=3 x=2
