Question

$$- 8 n + 3 ( m + n ) + 4 m =$$

Evaluate

$7m-5n$

Solution Steps

Use the distributive property to multiply $3$ by $m+n$.

$$-8n+3m+3n+4m$$

Combine $-8n$ and $3n$ to get $-5n$.

$$-5n+3m+4m$$

Combine $3m$ and $4m$ to get $7m$.

$$-5n+7m$$

Expand

$7m-5n$

Solution Steps

Use the distributive property to multiply $3$ by $m+n$.

$$-8n+3m+3n+4m$$

Combine $-8n$ and $3n$ to get $-5n$.

$$-5n+3m+4m$$

Combine $3m$ and $4m$ to get $7m$.

$$-5n+7m$$
