We know that GCF stands for Greatest Common Factor and hence we need to apply this in solving the given problem. The solution is shown below:
54x+8154x+81
Combine same terms, we have:
8208X+81
Factoring with the greatest common factor which is 27
304x+3
The answer for the factored expression is 304X + 3.
The commutative property states that you can invert the order of the terms of a sum:

So, if you start with

Applying the commutative property you'll get

Two equal fractions would be 4/6 and 6/9.
Try using 2 and 5.. 2x{[(12-3)x3]+(5x6)-8}=98
