Equation at the end of step1: (7x + 18) (4) - 4x = 0 2 STEP2:Equation at the end of step 2 2 • (7x + 18) - 4x = 0 STEP3:STEP4:Pulling out like terms
 4.1     Pull out like factors :
   10x + 36  =   2 • (5x + 18) 
Equation at the end of step4: 2 • (5x + 18) = 0 STEP5:Equations which are never true:
 5.1      Solve :    2   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
 5.2      Solve  :    5x+18 = 0 
 Subtract  18  from both sides of the equation : 
                      5x = -18
Divide both sides of the equation by 5:
                     x = -18/5 = -3.600

The answer is (7,6)
This is because a midpoint is in the exact middle, meaning that both sides are an equal distance away. You can find this by fining the difference between the two corresponding coordinates then adding that difference to the midpoint and that will give you your other endpoint. 
Hope this helped !!
