If the coefficient of X is a fraction, either of the following methods may be
used:
(1)
Divide both sides of the equation by the coefficient of X:
For example:
1 X = 20
2
NOTE:
The 1/2's cancel on the left side.
Then:
X = 20 X 2
1
1
X = 40
(2)
When the coefficient of X is a fraction, multiply both sides of the equal
sign by the denominator of the coefficient:
For example: 1 X
=
20
2
NOTE:
The 2's will cancel on the left side of the equal sign leaving:
X
=
20 (2)
X
=
40
e.
Example problem:
Multiply both sides of the equation by the denominator of the fraction:
