One-Step Equations!

Dear Families,

Today I introduced a new skill: solving one-step equations to find the value of a variable. We imagined a pan balance with some mass on each side and I explained how we need to keep the pan balanced in order for the equation to remain true. So long as we do that, we can do whatever we want to get the variable all on its own.

For example:

5 + x = 8

I can subtract 5 from each side:

5 + x = 8

-5       -5

and that leaves

      x = 3

We practiced using subtraction, addition, multiplication, and division today to isolate the variable on one side and its value on the other.

Here is a video that shows that same process that we practiced today and that we're practicing in homework: [link]

Warm regards,

Brian
