Question

$$(3x+7y-4)-(3 \times +5y-3)$$

Evaluate

$3x-8y-1$

Solution Steps

Multiply $3$ and $5$ to get $15$.

$$3x+7y-4-\left(15y-3\right)$$

To find the opposite of $15y-3$, find the opposite of each term.

$$3x+7y-4-15y-\left(-3\right)$$

The opposite of $-3$ is $3$.

$$3x+7y-4-15y+3$$

Combine $7y$ and $-15y$ to get $-8y$.

$$3x-8y-4+3$$

Add $-4$ and $3$ to get $-1$.

$$3x-8y-1$$
