Answer:The term X is a variable that takes the place of any number. ... If X stands for the number 13 then 2 times 13 is equal to 13 plus 13 which gives 26 when added. Similarly 2 multiplied by X results to X plus X which means a number added to itself since multiplication is a repeated addition. So 2X = 2 * X = X + X = 2X.
