Question 252374
This one appears a bit tricky. We have two equations and two unknowns:
{{{y(2x - 3y) = 19}}}
{{{x(3x - 4y) = 94}}}

step 1: divide the first equation by y and the second equation by x.

{{{(2x - 3y) = 19/y}}}
{{{(3x - 4y) = 94/x}}}

step 2: multiply the first equation by -1 and add the two equations together.

{{{-2x + 3y = -19/y}}}
{{{  3x - 4y = 94/x}}}

{{{x - y = 94/x - 19/y}}}

step #3: We can take the absolute value of both sides. absolute value (x-y) = 94/x - 19/y

I think this is what you are looking for?
