Solve the equation 3x + 5y = 15 for y.
a. y 3-x
b. y = 15 - 3x
c. y= 3(15 - 3x)
d. y - x - 3
v
=

I don't see this in any of your choices.

Please be sure the problem and choices are as you want them to be seen by others. Thanks kindly.  

I do hope my answer is helpful.

Step-by-step explanation:

We want to get the term that contains by itself.

This means we want to get by itself first.

To do this I need to get rid of the plus on that side.

I will do the inverse operation of that; I will subtract 3x on both sides.

-3x             -3x

since addition is commutative.

Now we have the 5y term by itself. We want the factor y in 5y by itself.

To undo multiplication you must divide.  We will divide both sides by 5:
