Answer:
7/13
Step-by-step explanation:
Let's call x= numerator
We know that :
Denominator= x+6
And
(numerator +2)/(denominator +2) = 3/5
So
(x+2)/(x+6+2)=3/5
(x+2)/(x+8)=3/5
(x+2)*5=(x+8)*3
5x+10=3x+24
2x=14
x=7
In the end
Numerator= x =7
Denominator=x+6 = 13
So the original number is 7/13

Answer:
Infinitely many solutions
Step-by-step explanation:
Left side:
When you distribute 1/2 to the equation in the parentheses, it will be 3x-3/2.
Right side:
When you distribute 1/4 to the equation in the parentheses, it will be 3x-6/4.
6/4 can be reduced to 3/2 so it'll be 3x-3/2.
This means that the reduced form will be 3x-3/2=3x-3/2
Since the 2 sides have the same equation, there will be infinitely many solutions.
