Question

Me podrían resolver las siguientes ecuaciones
-3x -1 = -22
-5y -8 = 12
3x + 8x = 44
2x + 4x = -42
-5h + 3h = -3 + 4
-10m + 15 = 170

Answer 1

- 3x - 1 = - 22

- 3x = - 22 + 1

- 3x = - 21

x = -21/-3

x = 7
------------------------------------

- 5y - 8 = 12

- 5y = 12 + 8

- 5y = 20

y = 20/-5

y = - 4
------------------------------------

3x + 8x = 44

11x = 44

x = 44/11

x = 4
-------------------------------------------

2x + 4x = - 42

6x = - 42

x = - 42/6

x = - 7
------------------------------------

- 5h + 3h = - 3 + 4

- 2h = 1

h = 1/-2

h = - 1/2
-------------------------------------

- 10m + 15 = 170

-10m = 170 - 15

- 10m = 155

m = 155/-10

m = - 31/2
