Question

can we add or subtract same number to both sides of an equation?

Answer 1

yes of course we can add or subtract same number to both side of an equation

Answer 2

Answer:

Step-by-step explanation:

This lesson explains how to solve an equation by adding or subtracting the same number to/from both sides of the equation. The basic rule is: in order to solve an equation, you use the additive inverse to isolate the term. Let's look at an example:

x - 5 = 8

To solve an equation like this, we have to see how we can get x by itself on the left side. This is where adding or subtracting the same number on both sides of the equation comes into play, and helps us solve the equation. adding (or subtracting) the same number to both sides of an equation does not change its solution set.
