Question

Hallen el valor de X.
1) -2 (x+1) = 8
2) 6x - 3 = 30 : (-2)
3) 7 (x-3)+4 = 10
4) 4-(x+6) = 10

Answer 1

Respuesta:

1)

-2 (x+1) = 8

-2x-2=8

-8-2=2x

-10=2x

x=-5

2)

6x - 3 = 30 : (-2)

6x-3=-15

6x=-12

x=-2

3)

7 (x-3)+4 = 10

7x-21=6

7x=27

x=27/7

4)

4-(x+6) = 10

4-x-6=10

-x-2=10

-12=x
