(25 points)
If y is proportional to x and y = -15 when x = -20, what is the value of x when y = 12?
Please show your work so I can understand how to solve!

Answers

Here, y = -15 with x = -20LCM of 15 & 20 is 60, so divide 15 & 20 from 60, 60/15 = 4 & 60/20 = 3Now, multiply the results with intial values, 4y = 3xy = 3/4 xWhen y = 12, x = 12 * 4/3x = 48 / 3x = 16In short, Your Answer would be 16Hope this helps!
