Post 8: Solving Two Step Equations

The next room holds a scale like the one before, except the x-side now carries a coefficient: 3x + 5. On the other side is a 11. One of the kids clears the +5 from both pans without a hitch and calls it solved. However, suddenly everyone starts seeing triple! Sage thinks he might know why...

Solving two step equations might seem difficult but it's basically just solving a One Step Equation twice. Here's an example:

As you can see, it's like a One Step Equation but you apply logic two times instead of one. Also, it helps to know that during this process you will use reverse PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction). That's why 4 was first added to both sides.

Good job finishing the problem.

Now try solving one more equation on your own. Click on the math and start typing to edit.

Congrats! You totally understand two step equations now.

Sage catches the mistake, divides the 3 off both pans, and everyone's vision returns to normal. As Sage follows the kids through the next door, he turns back and notices the shadowy figure has is closer than before, and that it is definitely the size of a kid.
