(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.
