what is a number that divied by 3 has a remainder of 2 also that smae number divided by 4 has a remainder 3 and that same number divided by 5 has a remainder of 4

i ment what is a number that divied by 3 has a remainder of 2 also that same number divided by 4 has a remainder 3 and that same number divided by 5 has a remainder of 4

It must be 2 more than a number evenly divisible by 3, such as
5,8,11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44, 47, 50, 53, 56, 59 ...
It must also be 3 more than a number evenly divisible by 4, such as
7,11,15,19,23,27,31,35,39, 43,47, 51, 55, 59...
It must also be 4 more than a number evenly divisble by 5, such as
9,15,19,24, 29, 34, 39, 44, 49, 54, 59, 64, 69..
The smallest number that satisfies all requirements is 59. There will probably be larger numbers also.

Here is another version of the famous Chinese Remainder puzzles which should give you an idea as to how to go about solving it. There are other methods.
Lets now attack the problem where three divisors and remainders are involved.
What is the smallest number that will leave a remainder of 1 when divided by 5, a remainder of 2 when divided by 7, and a remainder of 3 when divided by 9?
Let
1N/5 = A + 1/5 or N = 5A + 1
2N/7 = B + 2/7 or N = 7B + 2
3N/9 = C + 3/9 or N = 9C + 3
4Combining (1) and (2), 5A + 1 = 7B + 2 or 5A  7B = 1 or B = (5A  1)/7.
4Derive the first values of A and B by trial and error. Subsequent values of A differ by the coefficient of B or 7 and subsequent values of B differ by the coefficient of A, 5.
5A.....3.....10.....17.....24.....31.....38.....45
....B.....2......7.....12.....17.....22.....27.....32
6Combining (2) and (3), 7B + 2 = 9C + 3 or 7B  9C = 1 or C = (7B  1)/9.
7Derive the first values of B and C by trial and error. Subsequent values of B differ by the coefficient of C or 9 and subsequent values of C differ by the coefficient of B, or 7.
8B.....4.....13.....22.....31.....40.....49.....58
....C....3......10.....17.....24.....31.....38.....45
9Combining (3) and (1), 9C + 3 = 5A + 1 or 5A  9C = 2 or A = (9C + 2)/5
10Derive the first values of C and A by trial and error. Subsequent values of C differ by the coefficient of A or 5 and subsequent values of A differ by the coefficient of C, or 9.
11C.....2.....7.....12.....17.....22.....27.....32
.....A.....4....13....22......31....40.....49......58
12We must now search the tabular data to find a consistent set of values acrossall three tables.
13The lowest consistent set is A = 31, B = 22 and C = 17.
14This then leads to the minimum N = 5(31) + 1 = 7(22) + 2 = 9(17) + 3 = 156.
