Now we solve the proportion:
• 27*4 = 108
• 3*x = 4x
• 3x = 108
We solve for X by dividing 3 on both sides:
• 3x/3 = x
<span>• 108/3= 36

Our answer:
x = 36

Let the constant be k.
For an inverse squared proportion the formula is y = k/x^2
Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48
7a+20b = 28-b
7a = 28-b-20b
7a = 28-21b
a= 28/7 - 21/7 b = 4-3b
