There are two possible (and different) answers: 2x + 3y = 12 or 2*(x + 3y)= 12 The first one is (twice a number) increased by (three times another) The second is twice (a number increased by (three times another)).
The algebraic expression for twice a number ( n ) increased by 19 is ( 2n + 19 ). This expression represents taking the number ( n ), multiplying it by 2, and then adding 19 to the result.
The difference between a number x and twice y is equal to fifteen.

Generally, "twice" means double. So, twice X is equal to X plus X. Twice four is eight. simmisinghsaini's answer- But however, doesn't it mean to divide when we have to translate algebraic expressions?
