Resposta:

a) x = -2

b) x = -2

c) x = 1

d) x = -3

e) x = -5/2

f) x = -3

g) x = -6

Explicação passo a passo:

a)6×=2×-16

6x-2x = -16

4x = -16

x = -16/4

x = -4

b)2×-5=×+1

2x-x = 1+5

x = 6

c)2×+3=×+4

2x-x = 4-3

x = 1

d)5×+1=4×+10

5x-4x = 10-1

x = 9

e)4×-7=8×-2

4x-8x = -2+7

-4x = 5

x = -5/4

f)2×+1=4×-7

2x-4x = -7-1

-2x = -8

x = 8/2

x = 4

g)9×+9+3×=15

9x+3x = 15-9

12x = 6

x = 6/12

x = 1/2
