Solve one-step equations and interpret the solution in context.
Judge a solution check
Problem
Mia claims \(x~=~5\) satisfies \(x~-~2~=~1\). Substitute her value to evaluate the claim, then solve the equation. Report valid or invalid followed by the actual solution.
Big Picture
What this problem is really about
Evaluate the claim by replacing x with Mia's stated value in the original equation and comparing the two sides numerically. If they differ, the claim is invalid regardless of how plausible the value looks. Then solve the untouched equation with an inverse operation and verify the new value by substitution.
