Let x=total # of tickets needed to be sold

So if Six-sevenths of the total was sold, then we have the expression %286%2F7%29x

Since we are told that 82 tickets are left over, then we simply subtract the expression %286%2F7%29x (which is the number sold so far) from the total x to get 82:

x-%286%2F7%29x=82


%287%29%28x-%286%2F7%29x%29=%287%29%2882%29 Multiply both sides by the LCM of 7. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



7x-6x=574 Distribute and multiply the LCM to each side



x=574 Combine like terms on the left side




So that means that there are 574 tickets total


Now take six-sevenths of this total to get

%286%2F7%29574=492


--------------------------------------------------------------
Answer:

So 492 tickets have been sold so far.

Notice how 492 and 82 add up to 574. So this verifies our answer.

if:
x .....number of tickets
%286%2F7%29x....number of sold tickets
82.....were left over

then:
%286%2F7%29x+%2B+82+=+x………multiply both sides by 7
6x+%2B+82%2A7+=+7x
6x+%2B+574=+7x…..move 6x to the right
x+=+574

%286%2F7%29x+=++%286%2F7%29+574+=+%286%2A574%29%2F7+=+492………number of sold tickets
492+%2B+82+=+574
574+=+574
