Learning Objective
I can solve systems of linear equations using substitution.
- 1
The substitution method involves solving for one variable in one equation and substituting that expression into the other equation.
- 2
When using substitution, the goal is to create a single equation with one unknown variable.
- 3
After solving for one variable, substitute that value back into either of the original equations to solve for the remaining variable.
