How does using an inverse operation help you solve an equation?
*Please help*

Answers

Answer 1
Answer: An inverse set of operations is a pair of operations that do the opposite of each other, such as multiplication and division. When solving an algebraic equation, you can use inverse functions to isolate the variable you are trying to find.
For example:
5x=25
The expression 5x was arrived at by multiplying 5 times x. To reverse that multiplication, you would divide 5x by 5 and get x. However, since this is an equation, you would need to divide both sides of the equation by 5, or else it wouldn't still be equal. The result of dividing both sides is x=5.
As you can see, by taking the inverse operation, you were able to isolate your variable (x) on one side of the equation and therefore solve for its value.
Answer 2
Answer: it helps you check the equation to see if you did it right hopefully i helped :}
