ANSWER:

Suppose Sipho has x marbles. According to the given information, Mark has 3 times more marbles than Sipho, so Mark has 3 times more marbles.

If Mark gives Sipho 17 marbles, Mark will be left with (3x - 17) marbles. And this will be twice as many Sipho particles, i.e. x.

Therefore, we can write the equation:

3x - 17 = 2x

To solve x, we subtract 2x on both sides of the equation:

3x - 2x - 17 = 0

Simplify the equation:

x - 17 = 0

Added 17 to both sides:

x = 17

So Sipho has 17 marbles. Since Mark has 3 times as many marbles as Sipho, Mark has 3 * 17 = 51 marbles.

So Sipho has 17 marbles and Mark has 51 marbles.
