(y+1)/2 =-2(y+1)

\frac{y + 1}{2} = - 2 (y + 1)

y = - 1

Solution steps

\frac{y + 1}{2} = - 2 (y + 1)

Multiply both sides by

2

y + 1 = - 4 (y + 1)

Expand

- 4 (y + 1) : - 4 y - 4

y + 1 = - 4 y - 4

Move

1

to the right side

y = - 4 y - 5

Move

4 y

to the left side

5 y = - 5

Divide both sides by

5

y = - 1

2 x - 2 x y^{2}

- 10 < 2 - 4 n \leq 13

2 x^{3} - 200 x

16 (4 - 3 m) = 96 (- \frac{m}{2} + 1)

y, x^{2} + y^{2} + 4 x - 8 y + 20 = 0
