Question 1082260: hi can you help me understand how multiplying fractions by LCM simplifies this linear equation ?
even though i know how to do it but i dont understand how it works
this is a direct copy from a book
step 1+3x%2F2+=+x%2F5+-+39%2F5
step 2+%2810%293x%2F2+=+%2810%29x%2F5+-+%2810%29+39%2F5
result +15x+=+2x+-+78
+x+=+-6
my main problem with this is that when we multiply all the fractions by 10 it also has effects on the term x so i dont understand why it dosent change the result if you can please explain step by step how it works thanks.
