- ANS:THE NUMBERS ARE 25 AND 30
SOL:5B=6A.....====>5B/6
5(A-5)=4(B-5)
SOLVING EQUATION WE GET THE ANS - 12 years agoHelpfull: Yes(5) No(0)
- x/y=5/6
x-5/y-5=4/5
x=25
y=30 - 12 years agoHelpfull: Yes(3) No(0)
- (5x-5)/(6x-5)=4/5
x=5 - 12 years agoHelpfull: Yes(1) No(2)
- (5x-5)/(6x-5)=4/5
x=5
25 and 30 - 10 years agoHelpfull: Yes(0) No(0)
- x/y=5/6 => x=5y/6 (1)
x-5/y-5=4/5=> 5x-4y=5 (2)
after solve 1 and 2 get value of x=25 and y=30 - 10 years agoHelpfull: Yes(0) No(0)
- ans is 24,30
- 10 years agoHelpfull: Yes(0) No(1)
- ans is 25 and 30
5*x-5/6*x-5=4/5
x=5
5*5=25
5*6=30
