This is assuming that the question laid out the sequence of a calculation.
4y x 3y + z = 100
12y^2 + z = 100
Answer: 30 pairs of shorts
21x+420=35x
subtract 21x from both sides of the equation.
420=14x
get rid of the x by division
420/14
you get 30 =x
The answer to this question is sqrt(2)/2. Invoke the unit circle to derive this expression, or use special triangles and reference triangles.
