Lesson details

Lesson outcome

I can see that when an additive step and a multiplicative step are required to solve an equation, the order of operations will not affect the solution.

Show transcript
When an equation is in the form Ax + B = C you can solve by first subtracting B from both sides. When an equation is in the form Ax + B = C you can solve by first dividing both sides by A. These two options give the same solution. In any particular situation one way may be more efficient than the other and it useful to think carefully about this.
