Question
Find the first step in solving the following problem.
10x = 22
- Add 10 to each side
- Divide each side by 10
- Subtract 10 from each side
- Multiply by 10
Hint:
An operation that reverses the results of the original operation to isolate the variable in order to bring the equation to its simplest form is known as the inverse operation.
The correct answer is: Divide each side by 10
GIVEN-
10x = 22
TO FIND-
First step to isolate the variable in the given equation.
SOLUTION-
10x = 22
Since we have x which is multiplied with 10 in the LHS, to isolate x, we will have to reverse the effect of 10.
Hence, we will divide both the sides with 10 to simplify the given equation and isolate the variable x.
FINAL ANSWER-
Option 'b' i.e. 'Divide each side by 10' is the correct answer to the given question.
