Question

$$(-30)-(-(0)-(20)+c+2)$$

Evaluate

$-c-12$

Solution Steps

Subtract $20$ from $0$ to get $-20$.

$$-30-\left(-20+c+2\right)$$

Add $-20$ and $2$ to get $-18$.

$$-30-\left(-18+c\right)$$

To find the opposite of $-18+c$, find the opposite of each term.

$$-30-\left(-18\right)-c$$

The opposite of $-18$ is $18$.

$$-30+18-c$$

Add $-30$ and $18$ to get $-12$.

$$-12-c$$

Expand

$-c-12$

Solution Steps

Subtract $20$ from $0$ to get $-20$.

$$-30-\left(-20+c+2\right)$$

Add $-20$ and $2$ to get $-18$.

$$-30-\left(-18+c\right)$$

To find the opposite of $-18+c$, find the opposite of each term.

$$-30-\left(-18\right)-c$$

The opposite of $-18$ is $18$.

$$-30+18-c$$

Add $-30$ and $18$ to get $-12$.

$$-12-c$$
