Which expression is equivalent to 1/2x+(−7)−2 1/4x−(−2
Lynna [10]

The equivalent expression to the given expression is \mathbf{=-(\dfrac{7}{4}x+5)}

<h3>What is an algebraic expression?</h3>

Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).

From the given expression, we are to determine an expression that is equivalent to:

=\dfrac{1}{2}x + (-7) -2 \dfrac{1}{4}x -(-2)

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.

By doing so, we have:

=\dfrac{1}{2}x -7 -\dfrac{9}{4}x +2

=\dfrac{1}{2}x -\dfrac{9}{4}x +2 -7

=\dfrac{1}{2}x -\dfrac{9}{4}x -5

=-\dfrac{7}{4}x-5

\mathbf{=-(\dfrac{7}{4}x+5)}
