Question

despeja la variable de las siguientes ecuaciones

6x + 18 = 0
3x + 2 = 11
-25x = 75
10x = -1/2
9 - 7x + 18 = 12x - 10

Answer 1

Respuesta:

6x + 18 = 0

x = -18/6

x = -3

3x + 2 = 11

3x = 11 -2

3x = 9

x = 9/3

x = 3

-25x = 75

x = 75/-25

x = -3

10x = -1/2

x = -1/20

9 - 7x + 18 = 12x - 10

-7x - 12x = -10 - 18 - 9

-19x = -37

x = -37/-19

x = 37/19
