Question

Simplify.[5/(4x^2y)]-[y/(14xz)]
Someone please help me

Answer 1

\[\LARGE \cfrac{5}{4x^2y}-\cfrac{y}{14xz}=\]
\[\LARGE \cfrac{14xz \cdot 5 }{4x^2y\cdot 14xz }-\cfrac{y\cdot 4x^2y}{14xz\cdot 4x^2y}=\]
\[\LARGE =\cfrac{14xz \cdot 5 - y\cdot 4x^2y}{4x^2y\cdot 14xz }=\]
\[\LARGE =\cfrac{x(14z \cdot 5 - y\cdot 4xy)}{x^3y\cdot 56z }=\]
\[\LARGE =\cfrac{70z - y^2\cdot 4x}{x^2y\cdot 56z }\]
I don't know if this helps... I would call it more: "complicating" than "simplifying" ... lol
