1. form the ordered pair solution
If at least one of the variables is already solved for, use SUBSTITUTION!
Example:
STEPS:
SUBSTITUTE the expression from the solved variable
into _____________________________.
SOLVE
SUBSTITUTE that value into the original equation
and ________________________________.
The values of x and y __________________________________________.
CHECK the solution in ________________________________________.
*Remember: The solution to a system is an ordered pair (x , y) that makes the equation true.
the other equation
solve for the other variable
form the ordered pair solution
both of the original equations

Skyler has $70 in the bank and adds $5 each week.
Kyle has $50 in the bank and adds $10 each week.
In how many weeks will their account balances be the same? How much money will each of them have?
