Hello friends! Welcome to another exciting Math lesson!
Today we are going to go one step further in studying equations by looking at equations in 2 variables. Remember, this means there are two unknowns in the equation, so solving this equation would mean finding values for BOTH the variables that satisfy the equation. We will see what we can do to solve these equations. We will also look at what are called 'systems of linear equations' which are exciting because they are applied in numerous fields in life.
There's even more! We will also take a look at a fascinating geometric interpretation of linear equations in two variables. Let us start right away then! Come on!
