1. Answer:

   x-1/3 = k where k=3

   We must be happy enough to find the value of only one valuable here, that is, x.

   therefore, x-1/3=3

   To find what is x-1, all we need to do is,

   Take the denominator of the fraction to the answer (3)and multiply them. (that’s how you’ll find the values in the numerator)

   So, you’ll get,

   x-1=3*3

   x-1=9

   To find the value of x,

   The other number (-1) should be taken to the answer (9)

   (Remember that the sign changes when the number crosses the equals sign)

   therefore,

   x= 9 + 1 (-1 will turn to +1 on crossing the equal sign)

   Therefore , by addition, normally,

   you’ll get x=10

   Hope this helps:)
