Kyle decided to check his work after solving the equation - 4.0 + 2 = 10. He got the answer c = 2. Below is Kyles work for checking his answer Step 1: -43 + 2 = 10
Step 2: -4 (-2) + 2 = 10
Step 3: -8 +2 = 10
Step 4: -6 = 10
Based off of his work, he concluded that x does not equal to -2.
Analyze Kyle's work.
a. If Kyle did not check his work correctly, where did he go wrong?
b. What should his check work look like?
