Verified answer

resposta

a resposta é fração

x=1/2

Explicação passo-a-passo:

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

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

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

2x-x

2x-1x

(2-1)x

1x

x

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

x+1=5-x-3

x+1=2-x

2-x

-x+2

x+1=2-x

x+1=-x+2

x+1+x=2

x+x=2-1

x+x

(1+1)x

2x

x+x=2-1

2x=2-1

2-1

1

2x=2-1

2x=1

2x÷2=1÷2

x=1÷2

x=1/2

2x=1

x=1/2

resposta

x=1/2
