First : Distributive Property
(1/9∙x)+(1/9∙18)
1/9x+18/9
(1/3∙2x)+(1/3∙3)
1/9x+2+2/3x+1=x+3
Second : Rearrange
1/9x+2/3x-x+3-2-1
Third : Solve! :D
-7/9x=0
7/9x=0
x=0
Hey there!
First you need to see how much you need to buy, and when you do 10 x 12 = 120.
So you need at least 120 feet to cover the wall.
Now you have to factor in the wall, when you do 3 x 3 (B x H) = 9.
Now do, 120 - 9 = 111.
So you need 111 square feet to cover the wall.
Hope this helps!
