Hunter is going to paint a wall that measures 7 ft tall by 14 feet wide. The wall has two windows that are 1.5 feet wide by 3 feet tall. What is the area of the wall that he is going to paint?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
