# How do you combine (4d-2) - (d+1)?

Apr 12, 2018

$3 d - 3$

#### Explanation:

You distribute the negative, then combine the like terms. The "minus" outside the second parentheses is really a negative sign that applies to BOTH terms. So it would become:

$4 d - 2 - d - 1$

Combine like terms, making sure to carry the sign in front of each number or variable.

$4 d - d \text{ }$ and $\text{ } - 2 - 1$

so

$3 d - 3$

$3 d$ and $3$ are two separate things, so you cannot go any farther. ( do not subtract the $3$ from the $3 d$!)
