# How do you solve the equation -4x-7=17?

See explanation.

#### Explanation:

First yo ushould add $7$ to both sides to leave the unknown on left side:

$- 4 x = 24$

The last step is to divide both sides by the coefficient of $x$:

$x = \frac{24}{-} 4$

$x = - 6$

To check the solution you can substitute the calculated value to the original equation:

$- 4 \cdot \left(- 6\right) - 7 = 24 - 7 = 17$

Left and right sides are the same, so the answer is correct.
