sqrt(3y+21)-sqrt(y+20)=1

3 y + 21 - y + 20 = 1

y = 5

Solution steps

3 y + 21 - y + 20 = 1

Remove square roots

4 y^{2} = 4 y + 80

Solve

4 y^{2} = 4 y + 80 : y = 5, y = - 4

y = 5, y = - 4

Verify Solutions:

y = 5

True

, y = - 4

False

The solution is

y = 5

x^{\frac{3}{2}} = 3 x

3 x + 5 = 2

x^{2} - 2 x - 3 = 1 - x

9 x + 2 = 7 x + 18

x + 2 = 10
