Answer
False
Work Step by Step
False.
There are other ways to solve equations with decimals, such as to put the unknown factors on one side, combine similar terms, then divide all the factors by the appropriate number, in order to have 1X on one side.
For example
0.5X +X = 4.5
1.5X = 4.5
Divide both sides by 1.5
X = 3
