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\\(5y)/(5)=(d)/(5)-(5x)/(5)\\\mathrm{Simplify}\\y=(d-5x)/(5)`
