What is 13 minus X divided by seven equals six?

Answer 1

The way to approach this is to write a algebraic equation:

13 - (x/7) = 6

Times both sides by 7 which gives:

13 - x = 42

Take away 13 on both sides which gives:

-x = 29

x = -29

Now to check it

13 - - 29 = 42 (two negatives make a positive

42 divided by 7 = 6
