Linear equations, shown as (Ax + By = C), are used in many ways in our daily lives. Here are three examples:

1. Financial Planning:

   • When budgeting, we can use linear equations.
   • For instance, let’s say (x) stands for how much money you save, and (y) stands for your monthly expenses.
   • The equation (2x + 3y = 600) could help you figure out your savings goals.

2. Distance and Speed:

   • We can also use equations to figure out how far we travel.
   • If you’re moving at a steady speed, the equation (d = rt) shows how distance (d), rate (r), and time (t) can work together as a linear equation.

3. Mixing Solutions:

   • Mixing things, like making a drink, can also be explained with linear equations.
   • These equations can help us get the right amounts of different ingredients to get the flavors we want.

By understanding these examples, we can see how important linear equations are in making decisions in different situations.
