Mathematics

For x:

-2-3x=7+y             <em>add 2 to both sides</em>

-3x=9+y          <em>divide both sides by (-3)</em>

\boxed{x=-3-\dfrac{1}{3}y}


For y:

7+y=-2-3x      <em>subtract 7 from both sides</em>

\boxed{y=-9-3x}

Answer:

y = -3x-9

Step-by-step explanation:

To solve for y, we need to subtract 7 from each side

7-7 + y = -2-7 -3x

y = -3x-9

Hank estimated the width of the door to his classroom in feet. What is a reasonable estimate?
stiks02 [169]
2 feet, because you aren’t going to have a regular classroom door be 9 feet wide, or have it be 1 foot wide because there are some non really disabled kids but they still have wheel chairs and stuff and it won’t be easy for them to get through a door that is 1 foot wide.
