Question

three times a number decrease by 6 given 12 find the number​

Answer 1

Given: Three times a number decreased by$6$ gives$12$.

We have to find the value of a number.

We are solving in the following way:

Let assume the number will be$x$,

From the given statement, we can write:

$3x-6=12$

Solving the above equation:

$=>3x-6=12\\=>3x=12+6\\=>3x=18\\\\=>x=\frac{18}{3}$

Solving the above equation further we get,

$x=6$

Hence, the number will be$6$.

Answer 2

As per the data given in the Question,

We have to determine the value of required number.

As per question,

It is given that,

When Three times a number decreased by 6 gives 12.

So, for finding the value of required number.

Let us assume that the required number is x,

So, we can rewrite the above given equation in mathematical form as,

$3x-6=12$

Now solving the above equation,

We will get,

$=>3x-6=12\\=>3x=12+6\\=>3x=18\\=>x=\frac{18}{3}$

Solving the above equation further we get,

x=6

Hence, the number will be 6.
