Question

From 4 times a certain no. 12 is subtracted,then the result is equal to thrice the number together with 12.CAN YOU EXPLAIN IN STEPS......equations on simple equations

Answer 1

let the no. be x
4x-12=3x+12 (because its given that ans is 3 time the num. plu 12)
4x-3x=12+12
x=24
the number is 24

Answer 2

Let the number be x, Then
A.T.Q
4x-12=3x+12
-12-12=3x-4x
-x=-24
x=24                  [ - cancelled -]

Hence the number is 24.

Putting the value of x in the equation
4×24-12=3×24+12
96-12=72+12
84=84
 Hence verified.
