Solve for y (1)

100

4x + y = 5

y = -4x +5

200

4x + 2y = 8

y = -2x + 4

300

4x - y = 7

y = 4x - 7

400

2x - 3y = 9

y = 2/3 x - 3

500

x + 7y = -7

y = 1/7 x - 1

Solve for y (2)

100

x + y =7

y= -x +7

200

9x - 3y = 12

y = 3y - 4

300

3x -y =14

y = 3x - 14

400

x - y = 9

y = x - 9

500

x-4y =12

y = 1/4x - 3
