Question

Ashok and Gaurav has some marbles. Ashok said to Gaurav if you will give me ten marbles, I

will

have twice the marbles left with you. Represent this situation as a linear equation in two variables.​

Answer 1

Answer:

If ashok gives 'x' marbles to gaurav then ashok and gaurav would have A - x and G + x marbles.

A - x = G + x --- (1)

If Gaurav gives 2x marbles to Ashok then Gaurav and Ashok would have G - 2x and A + 2x marbles.

A+ 2x - (G - 2x) = 30 => A - G+ 4x = 30 --- (2)

From (1) we have A - G = 2x

Substituting A - G = 2x in (2)

6x = 30 => x = 5.
