Question

Which would be used to solve this equation? Check all that apply.
p/3=12

subtracting 3 from both sides of the equation
multiplying both sides of the equation by 3
dividing both sides of the equation by 3
substituting 4 for p to check the solution
substituting 36 for p to check the solution

Answer 1

The goal is to try to get "p" by itself on the left side of the equals sign

Answer 2

We can remove option A and D and E from the list, now what do you think is the answer?

Answer 3

if "3" is attached to the "p" with division
what should we do to "undo" that?

b and c

Answer 5

For example if it were attached with addition -> you would subtract to undo it
if it were attached with subtraction -> you would add to undo it
if it were attached with multiplication -> you would divide to undo it


so what would you do if you wanted to undo that division by 3?

Answer 6

Ok so it’s pretty easy

First multiply 3 on both sides

P/3 x 3 = 12 x 3

So the p/3 cancels out and your left with

P = 12 x 3

So multiply it

12 x 3 = 36

So

P = 36

So it’s B
