Question 571506: Ten times a certain number added five times another number is 170. If the first number less than the second number is 5, find the numbers. Answer by ikdeep(226) (Show Source):
You can put this solution on YOUR website! let the two numbers be x and y.
as per 1st condition;
10x + 5y = 170......(1)
as per 2nd condition;
x-y = 5
or x = y+5 ...........(2)
put the value of 'x' from (2) into (1) and we get,
[10(y+5)] + 5y = 170
solve the equation and we get;
y = 8
put the value of 'y' in (2) and we get;
x = 13
hope this will help you.
