How do you solve the system of equations #x+ y = 3# and #x = 3y - 5#?
You must make an equation that has only one variable in it so you can solve for that variable. By finding the variable you can use it to find the other one.
Let's solve for
Now we need to find
From the first equation, we can determine a value for
Divide both sides by
Note the each equation has a single
Therefore we can have:
There are now 2 ways to find a value for
