Answer: 1 gallon

Step-by-step explanation:

Hi there!

Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.

[(12*18)-(7*3)]/200

(215-21)/200

196/200

0.98

4) -4y= -x + 4<br> 6) y + 3x = 3
wel

Answer:

x=16/13

y= -9/13

Step-by-step explanation:

A:         -4y=-x+4

B:          y+3x=3

4B:       4y+12x=12

A+4B:   12x= -x+16

----->    13x=16

               x=16/13

-4y= -16/13+4

4y=16/13-4

y=4/13-1= -9/13
