Solve 4dy+12=7dy for y

Mathematics

Hi there!

Here are the steps into solving this equation :

4dy + 12 = 7dy

subtract 12 from each side of the equation

4dy = 7dy - 12

subtract 7dy from each side of the equation

-3dy = -12

divide each side of the equation by -3

dy = 4

divide each side of the equation by "d"

y = \frac{4}{d}


There you go! I really hope this helped, if there's anything just let me know! :)
