Question

$$[2x+(3x-5y+7z)]-2(5x-3z)$$

Evaluate

$13z-5y-5x$

Solution Steps

Combine $2x$ and $3x$ to get $5x$.

$$5x-5y+7z-2\left(5x-3z\right)$$

Use the distributive property to multiply $-2$ by $5x-3z$.

$$5x-5y+7z-10x+6z$$

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

$$-5x-5y+7z+6z$$

Combine $7z$ and $6z$ to get $13z$.

$$-5x-5y+13z$$

Expand

$13z-5y-5x$

Solution Steps

Combine $2x$ and $3x$ to get $5x$.

$$5x-5y+7z-2\left(5x-3z\right)$$

Use the distributive property to multiply $-2$ by $5x-3z$.

$$5x-5y+7z-10x+6z$$

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

$$-5x-5y+7z+6z$$

Combine $7z$ and $6z$ to get $13z$.

$$-5x-5y+13z$$
