Given : Expression 
To find : What is the value of x?
Solution :
Step 1 - Write the expression,

Step 2 - Cross multiply,

Step 3 - Take like terms together,

Step 4 - Solve,



Therefore, The value of x is -10.
I assume you want a common denominator.
So you see that the 5/12 has a denominator of 12, so you need to rename the 7 so it also has a denominator of 12.
7 is the same as 7/1. So multiply the numerator and denominator by 12 to get 84/12.
