Do you know how to solve systems of equations?
OpenStudy (breanna.rae):
no
OpenStudy (wolf1728):
Basically you multiply just one equation by a particular number to eleiminate one of the unknowns.
OpenStudy (breanna.rae):
ohh
OpenStudy (wolf1728):
Let's get the equation y=5x+7 and rearrange it to y -5x = 7 Then we see what multiplier we need to eliminate an unknown. We multiply y -5x = 7 by -3 Can you do that?
