Resolva as equações

20x-4=96

8x+4x=36

4x-12=2x-5

5(1-x)-2x+1=-3(2+x)

Answer 1

Resposta:

Explicação passo-a-passo:

I) 20x-4=96

20x=96+4

x=100/20

x=5

II) 8x+4x=36

12x=36

x=36/12

x=3

III)4x-12=2x-5

4x-2x= -5+12

2x= 7

x=7/2

IV)5(1-x)-2x+1=-3(2+x)

5-5x-2x+1=-6-3x

3x+3x=-6+6

6x=0

x=0/6=0
