Question

$$(-a+9b)-(-6a-b)=$$

Evaluate

$5\left(a+2b\right)$

Solution Steps

To find the opposite of $-6a-b$, find the opposite of each term.

$$-a+9b-\left(-6a\right)-\left(-b\right)$$

The opposite of $-6a$ is $6a$.

$$-a+9b+6a-\left(-b\right)$$

The opposite of $-b$ is $b$.

$$-a+9b+6a+b$$

Combine $9b$ and $b$ to get $10b$.

$$-a+10b+6a$$

Combine $-a$ and $6a$ to get $5a$.

$$5a+10b$$

Expand

$5a+10b$

Solution Steps

To find the opposite of $-6a-b$, find the opposite of each term.

$$-a+9b-\left(-6a\right)-\left(-b\right)$$

The opposite of $-6a$ is $6a$.

$$-a+9b+6a-\left(-b\right)$$

The opposite of $-b$ is $b$.

$$-a+9b+6a+b$$

Combine $9b$ and $b$ to get $10b$.

$$-a+10b+6a$$

Combine $-a$ and $6a$ to get $5a$.

$$5a+10b$$
