Answer 2

Resposta:

a) 5x-4=3x+16

5x-3x=16+4

2x=20

x=20/2

x=10

b) 6x-1+2x=4x+11

6x+2x-4x=11+1

4x=12

x=12/3

x=4

c) 3.(x-1)=2.(x+2)

3x-3=2x+4

3x-2x=4+3

x=7

d) y-8+5y= -3+2y+7

y+5y-2y= 7-3+8

4y=12

y=12/4

y=3

e) 5.(x-1)=2.(x+1)

5x-5=2x+2

5x-2x=2+5

3x=7

x=7/3

f) 9y-12=6y+9

9y-6y=9+12

3y=21

y=21/3

y=7
