The answer to this question would be x=a2y2
What's the question being asked here?
So for example 11/3 is 3 2/3 because you divide 11 by 3 and how you do it is that 3 goes into 11 3 times so you would write three on top of the 11 and then subtract 11-9 which is 2 so it is 3 2/3
Substitute the values into the equation
2(2)+4(-1)-5(1)
4-4-5
-5
