\( 1 \leftarrow \quad \begin{array}{l}\text { Solve for } \mathrm{x} \\ 55-3 x=7 \mathrm{x} \\ 5=\square \text { (Simplify your answer.) }\end{array} \)

To solve the equation \( 55 - 3x = 7x \), start by isolating \( x \). First, add \( 3x \) to both sides to get \( 55 = 7x + 3x \), simplifying to \( 55 = 10x \). Now, divide both sides by 10, giving \( x = 5.5 \). In a real-world context, knowing how to solve for \( x \) helps in budgeting and financial planning. For instance, if you're figuring out how much money you can save after spending a certain amount, setting up an equation similar to this can lead to insightful answers about your finances and help you stick to a budget!
