3 (y+9) = 12y+13 how many differnt solutions does it have?

(Choice A)

A

No solutions

(Choice B)

B

Exactly one solution

(Choice C)

C

Infinitely many solutions

Exactly 1 solution!

Choice B

Exactly 1 solution

Because:

First we must disrupte

3y+27=12y+13

Next we switch one number to the other side

27=9y+13

Now we must switch the other number

14=9y

Now we must solve by dividing 14 by 9

y=1.555

This is one solution, so we now have our answer.
