You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.
Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions.
9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)
then 9y = x [ 4(1+2y) ]
9y
therefore x = ------------
4(1+2y)
Solve for y using a similar approach.

Ok, there is no need to use a calculator for this.
Try and figure out what are the closest numbers for each one. For example, the first one, π, is lower than 4 but greater than 3. Therefore, it would be between 3 and 4.
I’m pretty sure it would be interquartile range, since range is the measure that measures variation within a data set.
