1. x=4+y-2z (move all terms not containing x to the right side of the equation) ; y= -4x + x + 2z (isolate) ; z= 2 - x/2 + y/2 (isolate)
2. y= 1/4x + 17/2 (slope intercept form)
3. x= -32/5 + 3y/5 + 2z ; y=32/3+5x/3-10z/3 ; z= 16/5+x/2 - 3y/10 (isolate the variable by dividing each side by factors that don’t contain variable)

 - The door to her room takes up 1.75 inches.
 - The longest wall in Jessica’s actual room is 15 feet long.
 2. Therefore, the actual size of the door is:
 15 feet=180 inches
 1.75 inches(180 inches/11 inches)=28.63 inches
 3. If the door in completely open, you must apply the formula for calculate the area of a semicircle:
 A=</span>πr²/2
 r=28.63 inches
 A=π(28.63 inches)²/2
 A=1288.11 inches²
 The answer is: 1288.11 inches²
