Question

A number decreased by 30 is the same as 14
decreased by 3 times the number. Find the number
​

Answer 1

Let the number be x.

Equation:

30-x = 3x-14

30+14 = 3x+x

44 = 4x

$\frac{44}{4}=x$

11 = x

Therefore the number is 11.

Check:

By putting the value of x as 11 in the equation:

30-11 = 3×11-14

19 = 33-14

19 = 19,

LHS = RHS

Hence Verified

⇒ The value of x or the number is 11.
