So your equation will be:
2(x+6) + 2(x+2) = 2(x+4) + 2(2x-2)
First, divide everything by 2
x+6+x+2 = x+4+2x-2
Then, combine like terms
2x+8 = 3x+2
Move the variables (the x's) to one side and the numbers to the other by subtracting 2x from one side and then 2 from the other
6 = 1x or 6 = x
Now that you know that x = 6, you go back to Earl's length and width equations
Length = x+2
Width = x+6
And plug in the value of x you got (6)
Length = 6+2 = 8
Width = 6+6 = 12
There are you answers! Hope this helped! (remember to add units, in this case the units are feet)
