# Solve the following equation −3x − 6 = 5x + 9.

We will use the concept of linear equations in order to solve the above equation.

## Answer: x = -15 / 8

Let us see how we will use the concept of linear equations in order to solve the above equation.

**Explanation**:

For the above equation that is −3x − 6 = 5x + 9

We will transpose 5x to the left-hand side and -6 to the right-hand side and then solve for x.

⇒ -3x - 5x = 9 + 6

⇒ -8x = 15
