*POR FAVOR ME AJUDEM*

Answer 1

Resposta:

a)4x-3-x+8=11

4x-x=11+3-8

3x=6

x=6/3

x=2

b)6.(x-2)=12

6x-12=12

6x=12+12

6x=24

x=24/6

x=4

c)10x+4.(5x-4)=21

10x+20x-16=21

30x=21+16

30x=37

x=37/30

x=1,23

d)10x+4.(3-2x)-6=8

10x+12-8x-6=8

10x-8x=8-12+6

2x=2

x=2/2

x=1

e)3.(5+3x)+5(6-5x)=22

15+9x+30-25x=22

9x-25x=22-15-30

-16x=-23 (-1)

16x=23

x=23/16

x=1,4375

f)2.(9x-4)-7+(6-5x).3=18

18x-4-7+3x=18

18x+3x=18+4+7

21x=29

x=29/21

x=1,380952381
