C. coincident



Answer :

Let's classify the system of linear equations:

[tex]\[ \begin{aligned} 2x &= 5 - y \\ -3 + y &= -2x + 3 \end{aligned} \][/tex]

First, we need to rewrite these equations in the standard form [tex]\(ax + by = c\)[/tex].

Starting with the first equation:

[tex]\[ 2x = 5 - y \][/tex]

We can move [tex]\(y\)[/tex] to the left side to get it into standard form:

[tex]\[ 2x + y = 5 \][/tex]

Next, let's look at the second equation:

[tex]\[ -3 + y = -2x + 3 \][/tex]

We can move [tex]\(2x\)[/tex] to the left side and constants to the right side:

[tex]\[ y + 3 = -2x + 3 \][/tex]

Now, adding [tex]\(-2x\)[/tex] and simplifying the right-hand side:

[tex]\[ 2x + y = 6 \][/tex]

We have the following system of equations in standard form:

[tex]\[ \begin{aligned} 2x + y &= 5 \\ 2x + y &= 6 \end{aligned} \][/tex]

To classify this system, we will consider the coefficients of [tex]\(x\)[/tex] and [tex]\(y\)[/tex] and the constants on the right-hand side.

Observing the two equations:
- The coefficients of [tex]\(x\)[/tex] (which are 2) are the same.
- The coefficients of [tex]\(y\)[/tex] (which are 1) are the same.
- The constants (5 and 6) are different.

With the coefficients of [tex]\(x\)[/tex] and [tex]\(y\)[/tex] being the same but the constants being different, this system represents parallel lines. Therefore, they do not intersect.

Thus, the correct classification of the system is:

parallel
