Multiply the terms

- 4 x^{6} \times x

Multiply the terms with the same base by adding their exponents

- 4 x^{6 + 1}

Add the numbers

- 4 x^{7}

- 4 x^{7} - 12 = 0

Move the constant to the right-hand side and change its sign

- 4 x^{7} = 0 + 12

Removing 0 doesn't change the value,so remove it from the expression

- 4 x^{7} = 12

Change the signs on both sides of the equation

4 x^{7} = - 12

Divide both sides

\frac{4 x ^{7}}{4} = \frac{- 12}{4}

Divide the numbers

x^{7} = \frac{- 12}{4}

More Steps

Evaluate

\frac{- 12}{4}

Reduce the numbers

\frac{- 3}{1}

Calculate

- 3

x^{7} = - 3

Take the 7 -th root on both sides of the equation

7 x^{7} = 7 - 3

Calculate

x = 7 - 3

Solution

x = - 73
