How to create an equation with a specific solution… Begin with a solution. Ok, let's just say x = 2 (this would represent the 2nd day of the month) Multiply each side by a constant . We'll just pick 3, so . x = 2. 3(x) = (2)3. 3x = 6 -----> You would STOP HERE for a one-step . Pick a number to add to BOTH sides of the equation. Hmm….
