Little Mammu and the Marbles

Algebra Level 3

Little Mammu was playing marbles with her friend Nawal. I heard her say to him , "if you give me one of your marbles I'll have as many as you". Nawal replied, "if you give me one of your marbles, and I'll have twice as many as you".

I wondered how many marbles little Mammu had! How many marbles did little Mammu have?


The answer is 5.

x + 1 = x − 1 x + 1 = x - 1 , and x − 1 = 2 x x - 1 = 2x .

We get x = 5 x = \boxed { 5 } .

?? m+1 = n -1 and 2(m-1)=n+1 are the two equations to solve.
