when x is divided by 7, the quotient is 26 and the remainder of this operation is 5 then it is the same to say that (x-5) divided by 7 is 26 so (x-5)/7=26 x-5=26*7=182 then x=187
Any number that can be divided evenly by 26 is a multiple of 26; i.e. 52, 78, 104, and130 can be divided by 26 with quotients of 2, 3, 4, and 5 respectively and without remainder. 26 itself is a multiple of 1 times 26 and of 2 times 13.
