Answer 1

Resposta:

a)6x=2x+16

6x-2x=16

4x=16

x=16/4

x=4

b)4x-10=2x+2

4x-2x=10+2

2x=12

x=12/2

x=6

c)2x+1=4x-7

2x-4x=-7-1

-2x=-8(-1)

2x=8

x=8/2

x=4

d)3x-2=4x+9

3x-4x=9+2

-x=11(-1)

x=-11

e)5x+4=3x-2x+4

5x+2x-4x=4-4

3x=0

x=0/3

x=0

f)x+x-4=17-2x+1

2x+2x=17+1+4

4x=22

x=22/4

x=11/2

g)3,4x-2,6=x-0,92

3,4x-x=2,6-0,92

2,4x=1,68

x=1,68/2,4

x=0.7

h)0,1x+3x+0,9x=14+2x

x+3x=14+2x

4x-2x=14

2x=14

x=14/2

x=7
