-n/7+19=-3 -n/7=-22 n/7=22 n=22(7) n=154
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
Let the number be 'n', then the calculation becomes :- 5/n - 3 = 7/2n . . . multiply throughout by 2n 10 - 6n = 7 6n = 3 n = 1/2
"n divided into 3" = 3/n
There are infinitely many such numbers. For example, 21*n + 1 will not be divisible by 7 or 3 for any n - no matter how large.

n = 157 157/7 = 22 remainder 3 or (22)(7) + 3 = 157 157/49 = 3 or (49)(3) = 157

7
3/n
It is: 3/n
no
n/7 = 12 Therefore, n = 12 x 7 n = 84
