Given: t is the midpoint of jk, jk= 5x-3 and jt =2x+1. determine the length of jk

(5x-3)/2 = 2x+1

1.  Multiply each side by 2. Result: 5x-3 = 4x + 2

2. To cancel out the -3, add positive 3 to each side. Result: 5x=4x+5

3. Subtract 4x from right side and do the same to the other side. Result: x = 5

All you then need to do is substitute x=5 into the original expression.  5(5) - 3 = 22

The length of JK equals 22.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
