Question

Multiply X by 3 and then subtract 3 from it if the result is 9 what is the value of x​

Answer 1

Answer:

Go through the operations in reverse order: You got 8 by multiplying something by 4, so that something must have been 2. But you got that something by substracting the number from 3, so substracting the number from 3 gives 2. That means that the number must have been 1.

$\huge\color{blue}\boxed{\colorbox{yellow}{x = 4}}$

Step-by-step explanation:

A.T.Q

$3(x) - 3 = 9$

$3x - 3 = 9$

$3x = 9 + 3$

$3x = 12$

$x = \frac{12}{3}$

$x = 4$
