IF X IS ADDED TO BOTH NUMENATOR AND DENOMINATOR IN FRACTION 2/3 AND 20/3,THEN FRACTION BECOME EQUAL.THE FACTOR OF X IS??
Read Solution (Total 10)
-
- (2+x)/(3+x) = (20+x)/(3+x)
if we cross multiplied then we get
x^2+5x+6 = x^2+23x+60
5x+6=23x+60
then 18x=(-54)
the value of x is -3 - 6 years agoHelpfull: Yes(13) No(0)
- (2+x)/(3+x)=(20+x)/(3+x)
6+5x+x^2=60+23x+x^2
18x=-54
x=-3 - 6 years agoHelpfull: Yes(2) No(1)
- i think it should be 0, because practically when you substitute 0 in both the fractions it will become equal but not with the other values

- x+2/x+3=20+x/3+x
x^2+5x+6=23x+x^2+60 - 6 years agoHelpfull: Yes(1) No(4)
- (2+x)/(3+x)=(20+x)/(3+x)
x^2+5X+6=x^2+23X+60
x=3 - 6 years agoHelpfull: Yes(1) No(11)
- 1->(x+2)/(x+3)=(x+20)/(x+23)
2-> cross multiply->(x+2)(x+23)=(x+3)(x+20)
3->(x^+23x+2x+46)=(x^+3x+20x+60)
4->25x+46=23x+60
5->25x-23x=60-46
6->2x=14

- Question is wrong or mistyped.

- (2+x)/(3+x)=(20+x)/(3+x).
then cross multiplication
then x value is 37 - 6 years agoHelpfull: Yes(0) No(4)
- sorry... please ignore my last comment. By mistake i read the question wrong, i read 20/3 as 20/30.
