Question

2(y-2)+5.(2-y)=-3(2y+2)

5.(y+1)-3.(2y+1)=4(5-y)

5-y-(2-y)-1=-(1-y)

Answer 1

Resposta:

1) y=-4

2) y=4

3) y=3

Explicação passo-a-passo:

2(y-2)+5.(2-y)=-3(2y+2)

2y-4+10-5y=-6y-6

2y-5y+6y=-6+4-10

3y=-12

y=$-\frac{12}{3}$

y=-4

5.(y+1)-3.(2y+1)=4(5-y)

5y+5-6y+3=20-4y

5y-6y+4y=20-5-3

3y=12

y=$\frac{12}{3}$

y=4

5-y-(2-y)-1=-(1-y)

5-y-2+y-1=-1+y

-y+y-y=-1-5+1

-y=-3

y=3

Por favor me avise qualquer divergência.
