Question

1) RESOLVA AS EQUAÇÕES:
a) 8 (x + 2) = 4 (x + 6)
b) 8 (x + 3) = 40
c) 10 (2x – 1) = 4 (x + 4)
d) 4x – 6 (4 – x) = 10 + 8 (2x + 1)
e) 4.(x + 3) – x = 24 + x

QUEM PUDER ME AJUDA NISSO MUITO OBRIGADO

Answer 1

a) 8 (x + 2) = 4 (x + 6)

8x+16 = 4x+24

8x-4x = 24-16

4x = 8

x = 8/4

x = 2

b) 8 (x + 3) = 40

8x+24 = 40

8x = 40-24

8x = 16

x = 16/8

x = 2

c) 10 (2x – 1) = 4 (x + 4)

20x-10 = 4x+16

20x-4x = 16+10

16x = 26

x = 26/16

x = 13/8

d) 4x – 6 (4 – x) = 10 + 8 (2x + 1)

4x-24+6x = 10+16x+8

4x+6x-16x = 10+8+24

-6x = 42

x =-42/6

x = -7

e) 4(x + 3) – x = 24 + x

4x+12-x = 24+x

4x-x-x = 24-12

2x = 12

x = 12/2

x = 6

Answer 2

1) RESOLVA AS EQUAÇÕES:

a) 8.(x + 2) = 4.(x + 6)
8X+16= 4x + 24
8x - 4x = 24 - 16
4x = 8
x = 8/4
x = 2
______________

b) 8. (x + 3) = 40
8x + 24 = 40
8x = 40 - 24
8x = 16
X = 16/8
X = 2
__________

c) 10.(2x - 1) = 4.(x + 4)
20x - 10 = 4x + 16
20x - 4x = 16+10
16x = 26 (:2)
8x = 13
X = 13/8
___________

d) 4x – 6 (4 – x) = 10 + 8 (2x + 1)
4x - 24 + 6x = 10 + 16x + 8
10x - 24 = 18 + 16x
- 24 - 18 = 16x - 10x
- 42 = 6x
6x = - 42
X = - 42/6
X = - 7
______________

e) 4.(x + 3) – x = 24 + x
4x + 12 - x = 24 + x
3x + 12 = 24 + x
3x - x = 24 - 12
2x = 12
X = 12/2
X = 6
