G)2x+1=4x-7
F)9x+9+3x=15

Answer 1

Resposta:

a) 4

b) 6

c) 1

d) 3

e) 6

f) -5/4

g) 4

h) 1/2

Explicação passo a passo:

a) 6x - 2x = 16

4x =16

x= 4

b) 2x - 5 - x = 1

2x - x = 1 + 5

x = 6

c) 2x + 3 - x = 4

2x - x = 4 - 3

x= 4 - 3

x = 1

d) 5x + 7 - 4x = 10

5x - 4x = 10 - 7

x = 10 - 7

x = 3

e) 4x - 10 - 2x = 2

4x - 2x = 2 + 10

2x = 2 + 10

2x = 12

x = 6

f) 4x - 7 - 8x = -2

4x - 8x = - 2 + 7

- 4x = - 2 + 7

-4x = 5

x = - 5/4

g) 2x + 1 - 4x = -7

2x - 4x = -7 -1

- 2x = - 7 - 1

- 2x = - 8

x= 4

h) 12x + 9 = 15

12x = 15 - 9

12x = 6

x = 1/2
