sqrt(x+5)+sqrt(3x+4)=7

x + 5 + 3 x + 4 = 7

x = 4

Solution steps

x + 5 + 3 x + 4 = 7

Remove square roots

4 x^{2} + 192 x + 2304 = 588 x + 784

Solve

4 x^{2} + 192 x + 2304 = 588 x + 784 : x = 95, x = 4

x = 95, x = 4

Verify Solutions:

x = 95

False

, x = 4

True

The solution is

x = 4

x = 12

10 = \frac{1}{2 x 1 - x ^{2}}

0.137 = Y^{\frac{1}{3}} \cdot 0.28

- (x + 1)^{\frac{4}{5}} + 2 = - 14

1 - \frac{1}{3} t^{- \frac{2}{3}} = 0
