Question

Calcular o valor de x:

Answer 1

b) 4x= 6x + 6
4x-6x= 6
-2x= 6 x(-1)
2x=6
x=6/2
x=3

c) 10+ 5x=3x-6
5x-3x=-6-10
2x=-16
x=-16/2
x=-8

d)6-3x=2x+8
-3x-2x=8-6
-x=2 x(-1)
x=2

Answer 2

a) x/4=6/3
     3x = 24
    x = 8

b)  2x/3 = (2x+2)/2
     6x + 6 = 4x
    6x-4x = 6
    2x = 6
x = 6/2
x= 3
