Let Z be the number

Z = 13x + 11 where x is the quotient when Z is divided by 13

Z = 17y + 9 where y is the quotient when Z is divided by 17

13x + 11 = 17y + 9

13x + 2 = 17y since x and y are quotients they should be whole numbers . Since y has to be a whole number the left hand side should be multiple of 17

The least possible value of x satisfying the condition is 9 and y will be 7

The answer is 13*9 + 11 = 128 or it is 17*7 + 9 = 128

This is the least number possible. There will be multiple answers and will increase in multiples 17*13 = 221 like 349 , 570, etc

Answer:

1) 2,(2) 3

Step-by-step explanation:

1) 2x+3/3x+4=7/10

10(2x+3)=7(3x+4)

20x+30=21x+28

20x-21x=28-30

-x=-2

x=2

2) 5x-1/4-2=5x-3/8

5x-1-8/4=5x-3/8

5x-9/4=5x-3/8

5x-9=(5x-3)×4/8

5x-9=20x-12/8

5x=20x-12/8+9

5x=20x-12+72/8

5x=20x+60/8

(5x)8=20x+60

40x-20x=60

20x=60

x=3
