Question

How can I write an equivalent expression by combining the like terms?-6 + (-2d) + (-4d) + 3d

Answer 1

`-6-3d`

Step-by-step explanation:

Given the below expression;

`-6+(-2d)+(-4d)+3d`

Let's go ahead and clear the parentheses by multiplying the addition sign by the subtraction sign. Note that the product of a positive and a negative sign is a negative sign as seen below;

`\begin{gathered} +*-=- \\ -*+=- \end{gathered}`

So the expression will now become;

`-6-2d-4d+3d`

Performing the indicated operations from left to right, we'll have;

`-6-3d`

So the equivalent expression is -6 - 3d
