This storyboard does not have a description.
So, 3 times 4 is 12 and 3 times X would be 3X, right?
I know the next step is to put together like terms. That means we have to do 12-2 and 12-2 equals 10.
Great that means we are down to 3X+10=19. Ok, next step, getting rid of the constant. That means subtracting 10 from ten to get 0 and 10 from 19 to get 9.
Yes, it is. Now the problem is 3X+12-2=19.
We're down to 3X=9, but what's the next step.
Well 3X is multiplication. To do the next step you do the opposite of the operation. Division is the opposite of multiplication.
