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.”
