Question

Resolva as equações abaixo:

a) x - 17 = 24


b) 2x + 10 = x - 24



c) - 6x = - 7x + 14


d) 5x + 12 - 4x = 21

E

e) 3x + 17 = 2x + 10


f) 6x - 14 = 5x - 23

Answer 1

a) x - 17 = 24

x= 24+17

x=41

b)2x + 10 = x - 24

2x - x = -24-10

1 x = - 34

x = -34

c)-6 x = -7x + 14

-6 x + 7 x = +14

1x = +14

x=14

d)5x + 12 - 4x =21

5x - 4x =21-12

1x = 9

x = 9

e)3x+17 = 2x +10

3x - 2x = 10-17

1x= -7

x = -7
