sqrt(8-y)-sqrt(y+5)=1

8 - y - y + 5 = 1

y = - 1

Solution steps

8 - y - y + 5 = 1

Remove square roots

4 y^{2} - 8 y + 4 = 4 y + 20

Solve

4 y^{2} - 8 y + 4 = 4 y + 20 : y = 4, y = - 1

y = 4, y = - 1

Verify Solutions:

y = 4

False

, y = - 1

True

The solution is

y = - 1

x - 1 = x + 5

2 5 x - 4 - 3 = - 11

x + 10 - 7 = - 5

x - 2 + 2 x + 3 = 8

x - 12 x + 35 = 0
