Hi there. :)
I'll try to make this simpler for you.
Let's focus on the equation from left to right, to avoid clutter.
-4(3 * 1/2) = -4(1.5)
Now to the right.
+ 2(3) = + 6
Now combine!
-4(1.5) + 6 =
-6 + 6 = 0
The answer is 0.
This is an example
Your length of the rectangle is 2 times the width.
Let length = 2x
Let width = x
Now your area = 450m^2
2x.x = 450 ("." means multiply)
2x^2 = 450
Therefore x^2 = 225
Therefore x= 15
If your x=15 , then you know your width.
Length = 2x (2 x 15 = 30)
Therefore:
Length = 30m
Width = 15m
Hope that helped! :)
