Question 155382
1. 2x+5y=2
5y=-2x+2
y=-2x/5+2/5
----------------------
2. -3x-2y=-5
-2y=3x-5
y=3x/-2-5/-2
y=-1.5x+2.5
---------------------------
3. x-2y=4
-2y=-x+4
y=-x/-2+4/-2
y=x/2-2
------------------------
4. -4x+y=5
y=4x+5

detirmine whether the given ordered pair is a solution to the system of equations?
