Question

$$5(4x-3y); -8(+x-3y)$$

Evaluate

$12x+9y-8$

Solution Steps

Use the distributive property to multiply $5$ by $4x-3y$.

$$20x-15y-8\left(1+x-3y\right)$$

Use the distributive property to multiply $-8$ by $1+x-3y$.

$$20x-15y-8-8x+24y$$

Combine $20x$ and $-8x$ to get $12x$.

$$12x-15y-8+24y$$

Combine $-15y$ and $24y$ to get $9y$.

$$12x+9y-8$$

Expand

$12x+9y-8$

Solution Steps

Use the distributive property to multiply $5$ by $4x-3y$.

$$20x-15y-8\left(1+x-3y\right)$$

Use the distributive property to multiply $-8$ by $1+x-3y$.

$$20x-15y-8-8x+24y$$

Combine $20x$ and $-8x$ to get $12x$.

$$12x-15y-8+24y$$

Combine $-15y$ and $24y$ to get $9y$.

$$12x+9y-8$$
