1)
5x+y=4
y = 4-5x
2)
3x-y=10
y = 10-3x
3)
4x+2y=10
2y = 10-4x /:2
y = 5-2x
4)
6x+3y=9
3y = 9-6x /:3
y = 3-2x
5)
3x-y=7
-y = 7-3x /:(-1)
y = -7+3x
6)
2x-2y=6
-2y = 6-2x /:(-2)
y = -3+x
5x+y=4
y=4-5x
3x-y=10
-y=10-3x
y=-10+3x
4x+2y=10
2y=10-4x/:2
y=5-2x
6x+3y=9/:3
2x+y=3
y=3-2x
3x-y=7
-y=7-3x
y=-7+3x
2x-2y=6
-2y=6-2x/:2
-y=3-x
y=-3+x
