​

Answer 1

Given:

Two variables are given as:

$3x$

$7x$

To find:

$\text{Sum\ of\ 3x\ and 7x}$

Solution:

First of all, Let us try to understand the given terms:

$3x$ and $7x$ are the two variables that contain a fixed part that is constant

And a variable part that can be any value as per the requirement.

The constant values are 3 and 7.

The variable part is $x$.

Now, let us try to find The sum:

$7x + 3x$

Here $x$ can be taken out as common and then simple addition of constant part can simply be added:

$x \times (7+3)\\\Rightarrow x \times 10\\\Rightarrow 10x$

The answer is:

$\therefore \text{Sum of 3x and 7x = 10x }$
