Question

Encontre o Valor do X

Answer 1

Resposta:

1) x= -5-11

x= -16

2)4x-2x= -10-20

6x= -30

x= -30/6

x= -5

3)5x+2x=24+4

7x= 28

x= 28/7= 4

4)7x-5x=9+5

2x= 14

x= 14/2 = 7

5) 5.(3x+10)=2.(x-1)

15x+50=2x -2

15x-2x=-2-50

13x =-52

x= -52/13 = -4

6)2.(2x+2)=3.(x+1)

4x+4=3x+3

4x-3x=3-4

x= -1

7)3x -4x=1+13

-x= 14

x= -14

8)4x-3x=7+3

x= 10

9)20x-15x=23+17

5x= 40

x=40/5 = 8

10)4.(x+1) = 3(x+2)

4x+4= 3x+6

4x - 3x = 6 -4

x= 2
