Solve the equation 3x + 5y = 15 for y.
Naddika [18.5K]

Answer:

y=\frac{-3}{5}x+3

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:

3x+5y=15

We want to get the term that contains y by itself.

This means we want to get 5y by itself first.

To do this I need to get rid of the plus 3x on that side.

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

3x+5y=15

-3x             -3x

5y=15-3x

5y=+15-3x

5y=-3x+15 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:

5y=-3x+15

------------------------------

            5

\frac{5y}{5}=\frac{-3x+15}{5}

y=\frac{-3x}{5}+\frac{15}{5}

y=\frac{-3}{5}x+3

Someone explain this step by step to me 1/2(c-8)=
polet [3.4K]

Answer: c/2-4


Step-by-step explanation:

This is what I get :

1/2(c-8)

Distributed property

1/2(c) + 1/2(-8)


Do c and -8 as a fraction with denominator 1 solve across

1/2×c/1+1/2×-8/1


Here you can only divide -8by 2

C/2-8/2

To get -4

C/2-4
