One-Step Equations and Inverse Operations

Key Questions

  • How do inverse operations help solve equations?

    They are helpful for solving with respect to a variable: if after some step you find yourself in a situation such as #\cos(x)=0.7#, if you want to find the value of #x# for which this statement is true, you need to apply the inverse cosine function at both sides and obtain #x=\cos^{-1}(0.7)#

  • How do you check solutions when solving one step equations?

    Answer:

    Substitute the solution for the variable in the equation and see if both sides of the equation are equal.

    Explanation:

    For example:

    #x+9=12#

    Subtract #9# from both sides.

    #x=12-9#

    #x=3#

    Now check by substituting #3# for #x# into the equation and solve.

    #3+9=12#

    #12=12# Check!
