Q. y=3x−5y=x−1Is (2,1) a solution of the system?Choose 1 answer:(A) Yes(B) No
Substitute and Check First Equation: First, we will substitute the point (2,1) into the first equation and check if it holds true. The first equation is y=3x−5. If we substitute x=2 and y=1, we get 1=3×2−5.
Substitute and Check Second Equation: After performing the calculation, we find that 1=6−5, which simplifies to 1=1, which is true. Therefore, the point (2,1) satisfies the first equation.
Point (2,1) Satisfies Both Equations: Next, we will substitute the point (2,1) into the second equation and check if it holds true. The second equation is y = x - 1 \. If we substitute \$ x=2 and y=1 , we get \(1 = 2 - 1 \.
Point (2,1) Satisfies Both Equations: Next, we will substitute the point (2,1) into the second equation and check if it holds true. The second equation is y=x−1. If we substitute x=2 and y=1, we get 1=2−1. After performing the calculation, we find that 1=1, which is also true. Therefore, the point (2,1) satisfies the second equation as well.
Point (2,1) Satisfies Both Equations: Next, we will substitute the point (2,1) into the second equation and check if it holds true. The second equation is y=x−1. If we substitute x=2 and y=1, we get 1=2−1. After performing the calculation, we find that 1=1, which is also true. Therefore, the point (2,1) satisfies the second equation as well. Since the point (2,1) satisfies both equations, it is a solution to the system of equations.
