Question

once to donkeys a and b were talking to each other .a said I can carry more snacks than you infact if you give me one of your snacks then I would have twice as many as you have.

linear equations in 2 variables​

Answer 1

Step-by-step explanation:

no. of snacks with donkey b=x

no. of snacks with donkey a=y

y=2x

Answer 2

Let mule and donkey carry x sacks and y sacks respectively.

Then the two statements mean:

If you give me one of your sacks, then I would have twice as many as you (i.e. if the mule

had one more and the donkey one less, the mule would have twice as many as donkey).

x + 1 = 2 (y - 1) = x - 2y + 3 = 0............... (1)

If I give you a sack, our loads would be equal (i.e. if the mule had one less and the

donkey one more, they would have the same number of sacks).

x - 1 = y + 1 = x - y - 2 = 0.........................(2)

Subtracting (i) from (ii), we get

y - 5 = 0 => y = 5.

Substituting y = 5 in (ii), we get

x - 5 - 2 = 0 = x = 7.

Hence, the mule was carrying 7 sacks and the donkey 5 sacks.
