The substitution method for solving a system substitutes an expression from one equation into the other.

SOLVING A SYSTEM USING SUBSTITUTION
Example: Solve
Check: Make sure the solution works for both equations in the system.
The solution is correct since it makes both equations true.
Workbook page 78
It’s very important that you use both equations when you are solving a system.
If you isolate the variable in the first equation, substitute the expression into the second.
Then put the solution from that step back into the first equation.
The equations are related, so you need to involve both to find the answer.
