Answer

no solution

Work Step by Step

Equation 1: $-3x + y = 5$ Equation 2: $-3x + y = -2$ Multiply equation 1 by $-1$: $$[-3x + y = 5]\cdot-1$$ $$3x -y = -5$$ Add this equation to equation 2: $$3x -y = -5$$ $$+$$ $$-3x + y = -2$$ $$=$$ $$0=-7$$ Since the sides are not equal, therefore there is no solution.
