Question

Resolva as equações
a) 2x + 11 = x
b) 3x + 1 = 2x
c) 1 + 2x = 8 - 5x
d) 5x - 1 = 2-X​

Answer 1

Resposta:

a) x = - 11

b) x = 1

c) x = 1

d) x = 0,5

Explicação passo-a-passo:

2x - x = 11

x = - 11

b)3x - 2x = 1

x = 1

c)2x + 5x = 8 - 1

7x = 7

x = 7 / 7

x = 1

d) 5x + x = 2 + 1

6x = 3

x = 3 / 6

x =
