If P is between J & K

This means that
\(JP + PK = JK\)

substitute what they are each equal to and you should get
\(3y + 1 + 12y - 4 = 75\)
from here we can solve for the variable \(y\)

first we can add like terms
\(15y - 3 = 75\)

then we can add 3 to both sides
\(15y = 78\)

then we divide both sides by 15
\(y = \frac{78}{15} = 5.2\)


so we have \(y = \frac{78}{15} = 5.2 \)
as our answer
