Students interpret equations like 1/x = 3 as two equations "1/x = 3" and "x ≠ 0" ” and “ ” joined by “and.” Students find the solution set for this new system of equations.
1. Rewrite the equation (x -2)/(x - 9) = 2 as a system of equations. Then, solve for x.
2. Write an equation that would have the restriction x ≠ -3.
