2.  This PowerPoint has a variety of algebraic
equations. Most are review of Algebra 1
equations; however, some may look unfamiliar
to you. Each equation type has its own
description page with links to videos. Watch
the videos explaining each equation type. Then
try solving each equation for x on your own
before clicking on a link to the solution of the
equation.

4.  The next three slides contain examples of
equations that only involve addition and
subtraction. Please view the video before you
work on the equations.

5.  To solve this equation we will subtract 1 from
both sides of the equation:
x=4
Quit

6.  Since we are dealing with subtraction we need
to add 9 to both sides yielding:
x=15
Quit

7.  In this form the equation is a little complicated.
First we need to combine the constants on the
left side of the equation:
9-5=4
 Our new equation is:
x+4=6
 Now we will subtract 4 from both sides:
x=2
Quit

8.  These equations involve multiplication and
division only.

2x=4
x/5=3
7/x=8
(5x)/10=2
Quit

9.  To solve for x we will divide 2 from both sides
of the equation:
x=2
Quit

10.  We will multiply each side of the equation by
5:
x=15
Quit

11.  Since x is in the denominator our first step is to
multiply both sides by x:
7=8x
 Now we will divide both sides by 8:
7/8=x
Quit

12.  We will start by multiplying both sides by 10:
5x=20
 Now we will divide both sides by 5:
x=4
Quit

13.  These equations combine addition, subtraction,
multiplication, and division.

14.  First we will add 3 to both sides:
5x=10
 Now we will divide both sides by 5:
x=2
Quit

15.  First we will subtract 6 from both sides:
x/2=2
 Now we will multiply both sides by 2:
x=4
Quit

16.  First we will multiply both sides by 2:
x+1=12
 Now we will subtract 1 from both sides:
x=11
