Y - 4 = 6

y = 6 + 4

y = 10

8 - z = 9 - z = 9 - 8 - z = 1

z = 1 / - 1

z = - 1

10 - x = 12 - x = 12 - 10 - x = 2

x = 2 / - 1

x = - 2

2x - 3 = 5

2x = 5 - 3

2x = 2

x = 2 / 2

x = 1

3y + 2 = 11

3y = 11 - 2

3y = 9

y = 9 / 3

y = 3

9x - 6 = 18

9x = 18 + 6

9x = 24

x = 24 / 9

x = 4 / 3

5x + 7 = 3

5x = 3 - 7

5x = - 4

x = - 4 / 5

1 - 4w = 9 - 4w = 9 - 1 - 4w = 8

w = 8 / - 4

w = - 2.
