Answer 2

Given :

» Fifteen added to thrice a while number gives 93.

To find :

• The number

Solution :

Let the number be x.

According to the question,

⟶ 3(Number) + 15 = 93

⟶ 3(x) + 15 = 93

⟶ 3x + 15 = 93

Transposing 15 to the right hand side and changing it's sign :

⟶ 3x = 93 - 15

⟶ 3x = 78

Transposing 3 to the right hand side :

⟶ x = 78/3

⟶ x = 26

⟶ The value of x = 26

Therefore, the number = 26

━━━━━━━━━━━━━━━━━━━━━━━━━

Let's verify :-

We can verify the value of the number by substituting it's value in the equation " 3(x) + 15 = 93" if the left hand side will be equal to the right hand side then the value of the number is right.

⟶ 3(x) + 15 = 93

⟶ Taking LHS :

⟶ 3(x) + 15

⟶ 3(26) + 15

⟶ 78 + 15

⟶ 93

LHS = 93

RHS = 93

LHS = RHS

Hence, verified!
