Answer 1

Q. If four is added to three times a number gives 19 . what is the number?

Solution :

Let the number be x
So,
According to the question,
4 will be added to 3 times the number x = 19

So,
Here's the equation

=> 3x + 4 = 19

=> 3x = 19 - 4

=> 3x = 15

=> x = 15/3

=> x = 5

Hence, the number x = 5

Verification :
LHS = 3x + 4
= 3*5 + 4
= 15+4
= 19 = RHS (verified)
