Simultaneous Equations
Simultaneous equations are equations that are occurring at the same time.
Basically what it’s asking you for is to solve for the variables.
First Step to Solving Simultaneous Equations
“Make 1 of the variables the same.”
In this case we made the “a” co-efficient the same.
Second Step to Solving Simultaneous Equations
“Solve for 1 of the variables.”
Third Step to Solving Simultaneous Equations
“Replace the first variable back into an equation and solve for the other variable.”
