a) 6x =2x +16
b)3x -2 = 4x +9
c)5x +4 =3x - 2x +4

Answer 1

a)6x-2x=16       4x=16            x-16/4       x=4

b)3x-4x=9+2        -x=11(-1)       x=-11

c)5x+4=x+4       5x-x=4-4         4x=0        x=o/4       x=0

Answer 2

Vamos lá Julia,

_____________

A)

6x = 2x + 16
6x - 2x = 16
4x = 16
x = 16 / 4
x = 4
_____________

B)

3x - 2 = 4x + 9
3x - 4x = 9 + 2
-x = 11
x = -11
_____________

C)

5x + 4 = 3x - 2x + 4
5x - 3x + 2x = 4 - 4
4x = 0
x = 0 / 4
x = 0
