Two Linear Equations in Two Variables: Solving Distances
Introduction

Systems of equations can help solve real-world problems involving two unknown quantities. By using two equations, we can find values that satisf...

You are solving a problem your math teacher gave you. John and Mike start at the same point and walk in opposite directions.

After some time, the distance between them becomes 20 km. Also, John has walked 2 km, more than Mike.

Let’s find out how far each of them has walked.

One way to find this is to use the substitution method...
