(7/10)  (d - 5/6 )  = 7  multiply both sides by 10/7

 

d  - 5/6  = 10       add 5/6 to  both sides

 

d  = 10 + 5/6  =     65/6

 

 

5c / 4  - 2c / 3  =  7/10     multiply through by the LCM of 4, 3 and 10  = 60

 

75c  -  40c  = 42

 

35c = 42    divide both sides by  35

 

c = 42/35   =  6/5
