Question

24 is divided into two parts such that 7 times the first part added to 5 time second part make 146 find each part

Answer 1

Let the first part be=x & second part be=y.

i;e. x+y=24

x=24-y  equation no:1

Now according to the question

7x + 5y=146 equation no:2

from equation no:1 we have x=24-y.Substituting this in equation no:2

7(24-y)+5y=146

168-7y+5y=146

168-2y=146

-2y=146-168

-2y= -22

y= -22/-2

y=11

Substituting y=11 in equation no:1

x=24-y

x=24-11

x=13

Therefore x=13,y=11.
