cube root of x+5}=2\sqrt[3]{2x+6

x = - \frac{43}{15}

Decimal Notation

x = - 2.86666 \dots

Solution steps

Take both sides of the equation to the power of

3 : x + 5 = 16 x + 48

x + 5 = 16 x + 48

Solve

x + 5 = 16 x + 48 : x = - \frac{43}{15}

x = - \frac{43}{15}

Verify Solutions:

x = - \frac{43}{15}

True

The solution is

x = - \frac{43}{15}

x + x - 5 = 1

3 x = x

x (1 - x) = 2 x - x 1 - x

x + 2 = 1 - 3 x + 7

0 = x + 2
