x −2=7
Try This• What does x equal? How can you show this? What do you
have to do to each side?
Try This• The zero pairs cancel each other out leaving x=9. In order to
keep our equation balanced we have to make sure to do the same thing to each side.
Try This• When working with variables we want to “isolate the variable”
getting it on one side of the equals sign and everything else on the other.
Try This• Try modeling this,
Try This• Now try to isolate the variable. Remember, you want to get
the x on one side of the equation and everything else on the other side. Also, remember, whatever you do to one side of the equation you must do to the other.
Try This• Now try to isolate the variable. Remember, you want to get
the x on one side of the equation and everything else on the other side. Also, remember, whatever you do to one side of the equation you must do to the other.
Try This• We are now left with x=4
Try This
2 x=6
Try This• Now arrange your tiles into equal groups
Try This• Now arrange your tiles into equal groups.
X=3
Try This
4 x−6=10
Try This• Now isolate the variable. Remember, whatever you do to one
side of the equation you have to do to the other to keep it balanced.
Try This• Now we need to put our tiles into equal groups to determine
what x equals.
