Question

Resuelve las siguientes ecuaciones:
2a -9 = -1
7m + 30 = -12
8b – 5 = 19
7 = 12 +5h
21 = 12z = -15
11 – 6k = -3
-3t – 15 = -9
24 -5w = 9
7x – 15 = 20
2x + 15 = 61
-5x + 600= 425
3x +3 = 108

Answer 1

Explicación paso a paso:

1- 2a -9 = -1 =4

2- 7m + 30 = -12 = m=-6

3- 8b - 5 = 19 = b=3

4- 7 = 12 + 5h = h=-1

5- 21 = 12z = -15

6- 11 - 6k = -3= k= 7/3

7- -3t - 15 = -9 = t=-2

8- 24 -5w = 9=

9- 7x - 15 =20=

10- 2x + 15= 61

11- -5x + 600=425 = x=35

12- 3x +3 = 108
