Question

How do you check the solution for two step equations?

Answer 1

Hint:To check the solution of any equation means the obtained solution will satisfy the given equation, means when you put the term in the equation it will give you the result as the left hand side of the equation is equal to the right hand side of the equation.

Complete step by step solution:
The answer for the given question is that after finding the roots or solution you have to put the obtained solution into the equation and check for the result as the left hand side is equal to right hand side in the given equation.
For more clarification let’s deal with a example as:
\[ \Rightarrow x + 2 = 0\]
For the given equation lets find the solution for the variable “x”, on solving we get:
\[
\Rightarrow x + 2 = 0 \\
\Rightarrow x = - 2 \\
\]
Here we got the single solution of the variable as “2” now to get verified that our obtained solution is correct or not we have to put the value in the given equation for the variable, on solving we get:
\[
\Rightarrow x + 2 = 0 \\
\Rightarrow ( - 2) + 2 = 0 \\
\Rightarrow 2 - 2 = 0 \\
\Rightarrow 0 = 0 \\
\]
Here we see that the left hand value is equal to the right hand value of the equation hence our obtained solution is correct.

Note:For obtaining the solution for any equation the steps involved is totally based, on the type of the equation given for finding the solution, but once you obtained the solution or roots of the equation then for verification you have to just put the solution in the given equation and see the equality of equation.
