In this post, I'm going to show how to solve a 2 step multiply, 2 step divide and a distributive equation. I'll also include a video I made on how to model each.
Co-efficient: It is the number, negative or positive, that you multiply the variable with.
Constant: These are the number parts of the equation. They stay the same.
Variable: A variable is a letter that represents an unknown number.
2 Step Multiply
opposite. Subtract 2 and divide by 3. You must do the same to 8 so the equation will be balanced.
verify to make sure you got it right.
2 Step Divide
In this case, you must add 3 and multiply 4 to isolate the variable. What you do on one side you do to the other.
Now verify to make sure it's correct.
Now all that's left to do is modeling!
Here is a short video I made
