Analyze Equations: Analyze the system of equations.We have the system:−2x+y=−52x−y=5We will first check if the equations are multiples of each other, which would indicate that they are the same line and therefore have infinitely many solutions.
Eliminate y: Add the two equations together to eliminate y.(−2x+y)+(2x−y)=−5+5This simplifies to:0=0Since the variables cancel out and we are left with a true statement, this indicates that the two equations are indeed the same line.
Conclude Solutions: Conclude the number of solutions. Because the two equations represent the same line, the system has infinitely many solutions.
