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)).
My number is 11.
Let the number be x and so if 2x = 12 then x = 6 and so 3x = 18
As an algebraic expression this is written 2x - 12, where x is the unknown number.
so the difference between twelve and -34 is 46. half of 46 is 23, That's your answer

twice the difference of three times a number and eight
A + 2a = 3a
three times a number decreased by eleven
The answer is 42
One.
18
John will be 16.
Krishna is 12 and three times as old as his brother, who must be 4. In 4 years time when Krishna is 16 he will be twice as old as his brother, who will then be 8.
2x+x=3x
n + 2n = 3n
The number is 7.
