Question

c)3x - 5 = x -2

d) 23x - 16 = 14 - 17x

e) 5x - 3 = 2x + 9

Answer 1

Resposta passo-a-passo:

C)

3x - 5 = x -2

3x - x = 5 - 2

2x = 3

x = 3/2

x = 1,5

D)

23x - 16 = 14 - 17x

23x + 17x = 16 + 14

40x = 30

x = 30/40

x = 0,75

E)

5x - 3 = 2x + 9

5x - 2x = 9 + 3

3x = 12

x = 12/3

x = 4
