5/6h - 7/12 = -3/4h - 13/6

-  =  - 

First, simplify  to  / Your problem should look like:  - =  - 
Second, simplify  to  / Your problem should look like:  -  =  - 
Third, multiply both sides by 12, which is the LCM of 6 and 4. / Your problem should look like: 10h - 7 = -9h - 26
Fourth, add 9h to both sides. / Your problem should look like: 10h - 7 + 9h = -26
Fifth, simplify 10h - 7 + 9h to 19h - 7 / Your problem should look like: 19h - 7 = -26
Sixth, add 7 to both sides. / Your problem should look like: 19h = -26 + 7
Seventh, simplify -26 + 7 to -19. / Your problem should look like: 19h = -19
Eighth, divide both sides by 19. / Your problem should look like: h = 
Ninth, cancel out 19. / Your problem should look like: h = -1

 h = -1
