When it comes to modeling linear equations, there are a few key points to keep in mind.

Firstly, ensure that you are using the correct variables in your equation.

Next, make sure your equation includes an equal sign, as this signifies that both sides of the equation are balanced and equal.

Common phrases that can help you translate words into mathematical expressions include "twice the value" (which means multiply by two), "more than" (which indicates addition), and "less than" (implying subtraction).

Lastly, being familiar with the US currency denominations can also be helpful when solving word problems involving money.
