Answer 2

Given,

$3(x - 3) = 15$

To find,

The value of x and its verification.

Solution,

The value of x in $3(x - 3) = 15$ will be 8.

According to the question,

We have the following expression:

$3(x - 3) = 15$

Multiplying 3 into the bracket,

3x-9 = 15

Moving 9 from the left-hand side to the right-hand side will result in a change of sign from minus to plus:

3x = (15+9)

3x = 24

x = 24/3

x = 8

Now, we will verify this value.

Putting this value of x on LHS:

3x-9

3(8)-9

24-9

15

Now, this value is equal to the value on R.H.S.

Hence, it is proved that the value of x in $3(x - 3) = 15$ is 8.
