<h3>Answer:</h3>

C. 4(x-3)-x

<h3>Step-by-step explanation:</h3>

All of the given expressions are equivalent to 3x+12 except selection C. Using that in your equation makes it be ...

... 3(x +1) +9 = 4(x -3) -x

... 3x +12 = 3x -12

... 12 = -12 . . . . . <em>false</em>

There is no value of x that will make this true, hence NO SOLUTION.

_____

<em>Comment on the other choices</em>

3x+12 = 3x+12 has an <em>infinite number of solutions</em>, as <u><em>any</em></u> value of x will make this true.

Which statement describes the graph of the system of equations?
qwelly [4]

Answer:

The lines are parallel.

Step-by-step explanation:

The first line is x-y=1

In slope-intercept form, this line has equation: y=x-1

The second line is y-x=1

In slope-intercept form, the line has equation: y=x+1

The slopes of the two lines are the same (m=1)

however, the y-intercepts of these lines are different (-1) and (+1) respectively.

The first choice is correct.

The two lines are parallel and hence will never intersect.
