Question

simplify: (5/4x^2y) - (y/14xz)

Answer 1

first find a common denominator so if we have:
\[5/(4x^{2}y)-(y/14xz)\]
we need to multiply everything in the left hand side by (7z/7z) and everything in the right hand side by (2xy/2xy) because the least common denominator for 14 and 4 is 28.
the result should look like this:
\[(35z/(28x^{2}yz))-(2xy^{2}/(28x^{2}yz))\]
now that we have a common denominator, we can combine them into:
\[(35z-2xy^{2})/(28x^{2}yz)\]

Answer 2

is this the final simplification?

Answer 3

you cant simplify anything more after that?
