Solving One-Step Addition Equations

In this video, Mr. J explains how to solve one-step addition equations by isolating the variable using inverse operations. The process involves undoing the addition by subtracting the same number from both sides of the equation to maintain balance. Two examples are provided: solving X + 16 = 28 and 57 = M + 20. Each example is followed by a verification step to ensure the solution is correct. The video concludes with a recap of the key steps in solving one-step addition equations.

What is the main goal when solving one-step addition equations?
