Question

if I add a number with 7 and it multiple with 3 then I get 36 then tell me what is a number???

Answer 1

LET THE NUMBER BE X
ATQ
3 ( X+7 ) = 36
3X + 21 = 36
3X = 36 - 21
3X = 15
X = 15/3
X = 5

Answer 2

Let the number be X.
A/Q ( X+7 ) 3 = 36
or 3X+21 = 36
or 3X = 36-21
or 3X = 15
therefore, X = 15/3 = 5
