Question 245073
so you have (h-h + 1)/4   =  (2h + 3)/5+1
            
Let us simplify first:

h-h is zero and 5+1=6

so  (0 + 1)/4   =   (2h + 3)/6    or       1/4 = (2h + 3)/6
  
Multiple both sides by 4   so   1 =   4(2h + 3)/6

now multiple both sides by 6 and simplify:

  6  =  8h +12     subtract 12 from both sides

  -6 = 8h    divide both sides by 8

-6/8 = h   reduce    -3/4 = h
