Let's build the equation counting how many x's and 1's are there on each side.
On the left hand side we have 5x's and 8 1's, for a total of 
On the left hand side we have 3x's and 10 1's, for a total of 
So, the equation we want to solve is

Subtract 3x from both sides:

Subtract 8 from both sides:

Divide both sides by 2:

If this number is well examined there are six 9s, four 6s, six 3s... If add up these numbers together it'll always give a multiple of three because the numbers itself(9,6,3)are multiple of 3. So the numbers you need to add are 8,2(twice) ,1 and 5..... 8+2+2+1+5=18... Hence the number is divisible by 3........
By definition, the area of a rectangle is given by:
Where
l: length of the rectangle
w: width of the rectangle
Therefore, substituting values we have:
Rewriting the expression we have:
