Question

2. Calcule o Valor de X nas questões a seguir:

B) -5(x-4)=60

E) -8. (x-1)= -16

Answer 1

B)

-5(x-4)=60

-5X + 20 = 60

-5X = 60-20

-5X = 40

-X = 40/5

-X = 8

x = -8

E)

-8. (x-1)= -16

-8X + 8 = -16

-8X = -16 - 8

-8X = -24 (x -1)

8X = 24

X = 24/8

X = 3

Answer 2

B) -5(x-4)=60

-5x + 20 = 60
-5x = 60 - 20
-5x = 40 (-1)
5x = -40
x = -40/5
x = - 8

E) -8. (x-1)= -16

-8x + 8 = -16
-8x = -16 - 8
-8x = -24 (-1)
x = 24/8
x = 3
