Question

Solve for y.


d = 5x + 5y




y=5x−d/5

y=d−5x/5

y=5(d−5x)

y=d−5x/x

Answer 1

Answer by Mimiwhatsup:

$\mathrm{Switch\:sides}\\5x+5y=d\\\mathrm{Subtract\:}5x\mathrm{\:from\:both\:sides}\\5x+5y-5x=d-5x\\Simplify\\5y=d-5x\\\mathrm{Divide\:both\:sides\:by\:}5\\\frac{5y}{5}=\frac{d}{5}-\frac{5x}{5}\\\mathrm{Simplify}\\y=\frac{d-5x}{5}$
