Question

quanto é a) x\2= 8 b)x\2 = -8 c)3x\4 = 9
d)2x\3 = -10 e)x+4\6 = 1 f)x-5\6 = 1
g 3x-1\5 = 2

Answer 1

A)
x/2 = 8
x = 8 * 2
x = 16

B)
x/2 = -8
x = -8 * 2
x = -16

C)
3x/4 = 9
3x = 9 * 4
3x = 36
x = 36/3
x = 12

D)
2x/3 = -10
2x = -10 * 3 
2x = -30
x = -30/2
x = -15

E)
x+4/6 = 1
x+4 = 1 * 6
x + 4 = 6
x = 6 - 4 
x = 2

F)
x-5/6 = 1
x - 5 = 1 * 6
x - 5 = 6
x = 6 -5 
x = 1

G)
3x -1 /5 = 2 
3x - 1 = 2 * 5
3x - 1 = 10
3x = 11
x = 11/3
x = 3,667...
