5If you had this equation,
how would you move
the 7
6to the other side
of the equation?
7You would subtract it . . .
. . . wouldnt you?
8This equation is probably
different from
other equations
you have solved.
9What makes it different?
It is different because
it has an x
on each side.
10How would you move
the x
from the right side
to the left?
11You would move the x
exactly the same way
you would move the 7.
12You would subtract it . . .
. . . wouldnt you?
13Now when you simplify. . .
14Now when you simplify. . .
15. . . the equation becomes
the type of equation
16. . . the equation becomes
the type of equation

20If you want to solve equations correctly
(and you do)
(Dont you?)
you will get in the habit
of checking solutions.
21Checking the solution
Good solution!

23Try this one
Check your work !
Good solution!
24You say you want one more?
Okayheres one more.
Did you check you answer?
If you did, you know the solution is
