After plotting all the points, the only one that makes sense is (4,3).
b= 2 and 5
is your answer to the above question.
Answers:
2x - 6y = 8 -> x = 4 + 3y
-3x + 9y = 12 -> x = -4 + 3y
We can do this by using either long division or synthetic. I will use synthetic because it saves time. 6x^3-37x^2+32^x+15.
