Sara says "If you subtract 11 from my number and multiply the difference by -3 , the result is -54 ." What is Sara's number?

Statement given :

→Sara says "If you subtract 11 from my number and multiply the difference by -3 , the result is -54 .

To find :

SOLUTION :

Let us take Sara's Number be “x”.

★According to Question,

→ x - 11×(-3)= -54

→ x + 33 = -54

→ x = -54-33

→ x = (-87)

let's verify our number,and check whether it's correct or not !

x - 11×(-3)= -54

Putting the value of x

(-87) - 11 × (-3)= -54

(-87) + 33 = -54

(-54) = -54

Hence, The L.H.S. = R.H.S.

Thus,our number is Verified.
