ajuda nois ae pfv

x = 2-4x

26+x = -5x

5x = x+12

5x+4 = x+12

​

Answer 1

Explicação passo a passo:

a) x = 2-4x

x + 4x = 2

5x = 2

x = 2/5

b) 26+x = -5x

26 = -5x - x

26 = -6x

-(26/6) = x

-(13/3) = x

c) 5x = x+12

5x -x = 12

4x = 12

x = 12 / 4

x = 3

d) 5x+4 = x+12

5x - x = 12 - 4

4x = 8

x = 8/4

x = 2
