Who likes reading bts fanfic if so read mine I just posted it yesterday Happy Birthday to Me
this is its summary
Today is Jimin's birthday, although no one remembered until RM reminded everyone. As everyone left to get him something special, Jimin went off his own to find something that's special to him. He does find something he wants, but he's too shy to get it.

Never read any fanfic bts before but yeah it was a good read maybe a lil longer would've been better.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
