Q. How many solutions does the system have?{5x−y=25x−y=−2Choose 1 answer:(A) Exactly one solution(B) No solutions(C) Infinitely many solutions
Analyze equations' structure: Analyze the structure of the equations.We have the system of equations:5x−y=2 ...(1)5x−y=−2 ...(2)Both equations have the same coefficients for x and y, which means they have the same slope.
Compare constants on right side: Compare the constants on the right side of the equations.Equation (1) has a constant of 2, and equation (2) has a constant of −2.Since the constants are different, the lines represented by these equations are parallel.
Determine number of solutions: Determine the number of solutions for parallel lines.Parallel lines never intersect, so there are no points that satisfy both equations simultaneously.Therefore, the system of equations has 0 solutions.
