sqrt(9y+9)-sqrt(y+1)=4

9 y + 9 - y + 1 = 4

y = 3

Solution steps

9 y + 9 - y + 1 = 4

Factor

9 y + 9 - y + 1 : 2 1 + y

2 1 + y = 4

Divide both sides by

2

1 + y = 2

Square both sides:

1 + y = 4

1 + y = 4

Solve

1 + y = 4 : y = 3

y = 3

Verify Solutions:

y = 3

True

The solution is

y = 3

2 x - 1 = 3

3 x - 2 + 7 = 6

x + 4 = 2 - x

3 y + 15 + 3 = y + 2

x^{\frac{3}{2}} = x^{2} - 14 x + 48
