Do the equations x = 4y + 1 and x = 4y – 1 have the same solution? How might you...

The equations x=4y+1 and x=4y-1 have no solutions in common.
Graphically, these are parallel lines and thus have no common points.
Numerically, it is clear that for any given y, 4y+1>4y-1 so the associated x-values cannot be the same.
