Question

Two times of a number subtracted from 3 to equal 9 . Express this statement as a linear equation in one varaible by taking varaible​

Answer 1

Given: Two times of a number subtracted from $3$to equal $9.$

We have to write a linear equation of the given statement.

For this, we will assume the number as $x$ variable, and then we will solve the equation.

We are solving in the following way:

We have,

Two times of a number subtracted from $3$to equal $9.$

Now,

Let assume the number will be$x.$

Then,

$=>3-2x=9\\=>3=2x+9\\=>2x+9=3$

Hence, the linear equation will be$2x+9=3.$

Answer 2

As per the data given in the question,

We have to write the linear equation for the expression -  Two times of a number subtracted from 3to equal 9.

For writing the linear equation,

we will assume that the number as x variable, and then we will solve the equation.

As from question,

It is given that,

Two times of a number subtracted from 3 to equal 9.

So,  

Let assume the number will be x.

Hence, above expression can be mathematically written as,

$=>3-2x=9\\=>3=2x+9\\=>2x+9=3$

Hence, the linear equation will be2x+9=3.
