Title: Solving


1
Solving
Equations
2
with Variables
3
on Both Sides
4
Solving Equations with Variables on Both Sides
5
If you had this equation,
how would you move
the 7
6
to the other side
of the equation?
7
You would subtract it . . .
. . . wouldnt you?
8
This equation is probably
different from
other equations
you have solved.
9
What makes it different?
It is different because
it has an x
on each side.
10
How would you move
the x
from the right side
to the left?
11
You would move the x
exactly the same way
you would move the 7.
12
You would subtract it . . .
. . . wouldnt you?
13
Now when you simplify. . .
14
Now when you simplify. . .
15
. . . the equation becomes
the type of equation
16
. . . the equation becomes
the type of equation
17
that you already know
how to solve.
18
that you already know
how to solve.
19
that you already know
how to solve.
20
If you want to solve equations correctly
(and you do)
(Dont you?)
you will get in the habit
of checking solutions.
21
Checking the solution
Good solution!
22
Try this one
23
Try this one
Check your work !
Good solution!
24
You say you want one more?
Okayheres one more.
Did you check you answer?
If you did, you know the solution is
