SP5 unit J concept 6-solving systems of equations that have repeating denominator s.

Hello this is Ana from Period 4. Some thibgs that ypu must be careful of when solving this problem is making sure that our distribution is correct. Also. When combining like terms to make sure that the addition and subtraction are correct. we muat be very caregul when it comes to the signs. When pluggibg it into the graphing calculator to use RREF and after plug in the A B and C into the decomposed part of the problem. When checking your answer we mulitiply the common denomitators to the bottom if everythibg cancels out to add to the original numerator.
I hoped this helped. Thank you.
