Chemist0 $4-x = 5x + 22

-x - 5x = 22 - 4

-6x = 18

x = -3$

$5y + 18 = 8y

5y - 8y = -18

-3y = -18

y = 6$

$16 - 2x = 3x

-2x - 3x = -16

-5x = -16

x = 3.2$

$42 - 2x = 5x

-2x - 5x = -42

-7x = -42

x = 6$

$3x + 18 = 5x

3x - 5x = -18

-2x = -18

x = 9$

$5y - 22 = 3y

5y - 3y = 22

2y = 22

y = 11$

$3x+38=5x+18

3x - 5x = 18 - 38

-2x = -20

x = 10$

$7y - 5 = 3y + 3

7y - 3y = 3 + 5

4y = 8

y = 2$

$6x - 45 = 2x - 17

6x - 2x = -17 + 45

4x = 28

x = 7$

$3-3y=7-13y

-3y + 13y = 7 - 3

10y = 4

y = 0,4$

$3x - 2 = 7 - x

3x + x = 7 + 2

4x = 9

x = 2.25$
