Question

genteeeee socorroooo tenho 10 minutos a) X - 17 = -9
b) 2x = -7
c) 3x + 2 = 2x - 11
d) 2x = 16
e) 2x + 14 = 5x - 1
f)5x + 4 - 2x = 26 - 3x
g) 5m - 7 - 2m - 2 = 0​

Answer 1

Resposta:

a) x - 17 = - 9

x = 17 - 9

x = 8

b) 2x = -7

x = -7 ÷ 2

x = - 3,5

c) 3x + 2 = 2x - 11

3x - 2x = -11 - 2

x= - 13

d) 2x = 16

x= 16÷2

x= 8

e) 2x + 14 = 5x-1

14 + 1 = 5x - 2x

15 = 3x

x = 15 ÷ 3

× = 5

f) 5x + 4 - 2x = 26- 3x

5x - 2x + 3x = 26 - 4

6x = 22

x = 22 ÷ 6

x = 3,66...

g) 5m - 7 - 2m - 2 =0

5m - 2m = 0 + 7 + 2

3m = 9

m = 9 ÷3

m = 3

Answer 2

Explicação passo-a-passo:

a) x -17 = -9

x = 17 -9

x = 8

b) 2x = -7

x = -7/2

x = -3,5

c) 3x + 2 = 2x - 11

3x - 2x = -11 -2

x = -13

d) 2x = 16

x = 16/2

x = 8

e) 2x + 14 = 5x - 1

2x - 5x = -1 -14

-3x = - 15

x = -15/-3

x = 5

f)5x + 4 - 2x = 26 - 3x

5x -2x +3x = 26 -4

6x = 22

x = 22/6

x = 3,66

g) 5m - 7 - 2m - 2 = 0

5m -2m = 7 +2

3m = 9

m = 9/3

m = 3
