It is: 3x = 2x+8 and the value of x is 8
let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
three times a number decreased by eleven
One.

A + 2a = 3a
2x+x=3x
n + 2n = 3n
twice the difference of three times a number and eight
2x - 16 = 3x/18
It is: 3x = 2x+8 and the value of x is 8

let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
three times a number decreased by eleven
The answer is 42
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)).
One.
