The statement does not make sense.

Work Step by Step

We know that a system of linear equations contains two or more linear equations that have to be dealt with all together and the general form of the linear equation is $y=mx+c$, where m is the slope of the line. Now, consider the following system of equations: $x+3y+2z=8$ (I) $y=5x+1$ (II) $z=3x+2$ (III) Here, equations (II) and (III) are in the form $y=mx+c$ and equation (1) can be transformed into its slope-intercept form. Thus, the provided statement makes no sense.
