Question

$$(9-5x)-(5x-9)$$

Evaluate

$18-10x$

Solution Steps

To find the opposite of $5x-9$, find the opposite of each term.

$$9-5x-5x-\left(-9\right)$$

The opposite of $-9$ is $9$.

$$9-5x-5x+9$$

Combine $-5x$ and $-5x$ to get $-10x$.

$$9-10x+9$$

Add $9$ and $9$ to get $18$.

$$18-10x$$

Expand
