marbles as
Sipho
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.
