Question

resolva as equação 9-3x=-5+4x b)5×-1=4x+3 c)5x-6=3-4x​

Answer 1

Resposta:

a) 9 - 3x = - 5 + 4x

x = 2

b) 5x - 1 = 4x + 3

x = 4

c) 5x - 6 = 3 - 4x​

x = 1

Explicação passo-a-passo:

a) 9 - 3x = - 5 + 4x

9 + 5 = 4x + 3x

14 = 7x

14 / 7 = x

x = 2

b) 5x - 1 = 4x + 3

5x - 4x = 3 + 1

1x = 4

x = 4 / 1

x = 4

c) 5x - 6 = 3 - 4x​

5x + 4x = 3 + 6

9x = 9

x = 9 / 9

x = 1
