d.

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

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

The 2's will cancel on the left side of the equal sign leaving:

X

=

20 (2)

X

=

40

e.
