Question 580208
I'm assuming you want to solve for y.



{{{50x-40y=200}}} Start with the given equation.



{{{-40y=200-50x}}} Subtract {{{50x}}} from both sides.



{{{-40y=-50x+200}}} Rearrange the terms.



{{{y=(-50x+200)/(-40)}}} Divide both sides by {{{-40}}} to isolate y.



{{{y=((-50)/(-40))x+(200)/(-40)}}} Break up the fraction.



{{{y=(5/4)x-5}}} Reduce.
