Find the LCM of the denominators. In this case, 42 is the LCM.
Multiply every term by 42.
As you can see everything will no longer be a fraction since we made sure each denominator divides the number we multiplied (42) evenly.
To check plug 9/10 back in for x
Common Denominator : 210
TRUE
9/10 is most definitely our answer.
