![]() ![]() ![]() To check our work, take the answer of 68 and go through the different operations as described by the important pieces of the word problem.Ħ8 original baseball cards (our answer) + 8 new baseball cards Dan bought = 76 total cards. And then, whatever we do to one side of the equation we must do to the other side of the equation.Īfter multiplying both sides by 2, we are left with C+8 = 76.meaning we are very close to finding C on its own!įrom there, we need to subtract 8 from both sides, ultimately leaving us with our pre-checked answer of C=68! In this case, we are dividing C+8 by 2, so we must multiply as the inverse. Now, we are ready to solve! To get C by itself, we must perform inverse operations. Last, we know that Dan ends up with 38 cards in the end, so we set it equal to 38. Next, because Dan's dog ate half of the collection, we divide everything by 2. ![]() (Here is more on converting word problems into equations.) Next, begin writing the equation by breaking down the important pieces of the problem.įirst, Dan bought eight new cards, so we add C+8. Step Three: Write your equation(s) by breaking down the text of the problem The unknown, or what we are trying to solve for is C, or the number of cards Dan started with. Step Two: Define your variable(s) or unknowns These valuable details usually include all numbers and any indication that something is being added, subtracted, divided, or multiplied. Go through the problem and identify the important pieces. How many cards did Dan start with? Step One: Highlight important parts of the text There are now only thirty eight cards left. The next day, his dog ate half of his collection. Solve for X Math Tutorial Solving Two Step Equation Word Problemsĭan bought eight new baseball trading cards to add to his collection.
