Question

Resolva as equações.
a) 92x-1 = 1
b) 6.7x-3 = 294
c) 31+x = 324-3
d) 2x+2+2x-1=36​

Answer 1

Resposta:

a) 1/42

b) 99/14

c) 290

d) 35/4

Explicação passo-a-passo:

a) 92x - 1 = 1

92x = 1 + 1

92x = 2

x = 2/92

Simplificando ...

x = 1/42

b) 6 . 7x - 3 = 294

42x = 294 + 3

42x = 297

x = 297/42

Simplificando ...

x = 99/14

c) 31 + x = 324 - 3

x = 324 - 3 - 31

x = 290

d) 2x + 2 + 2x - 1 = 36

4x = 36 - 2 + 1

4x = 35

x = 35/4
