Question

saben la respuesta de 7 = 12 + 5h son varias perdon y tambien las respuestas de 24 - 5w = 9 y 3t - 15 = -9 y 11 - 6k = -13 y 21 = 12z -15 y 7x - 15 = 20 y 3x + 3 = 108 y 2x + 15 = 61 y ya nadamas esta de 5x + 600 = 425

Answer 1

5h + 12 = 7

5h = 7 - 12

5h = -5

h = 5/5 = -1

24 - 5w = 9

5w = 9 - 24

w = -15/5

w = -3

3t - 15 = -9

3t = 15 - 9

t = 6/3

t = 2

11 - 6k = -13

6k = -13 - 11

k = -24/6

k = -4

21 = 12z - 15

21 + 15 = 12z

36/12 = z

z = 3

7x - 15 = 20

7x = 20 + 15

x = 35/7

x = 5

3x + 3 = 108

3x = 108 - 3

x = 105/3

x = 35

2x + 15 = 61

2x = 61 - 15

x = 46/2

x = 23

5x + 600 = 425

5x = 425 - 600

x = - 175/5

x = -35
