Q. y=2x+1x−y=−3Is (2,5) a solution of the system?Choose 1 answer:(A) Yes(B) No
Substitute and Check First Equation: First, we will substitute the point (2,5) into the first equation and check if it holds true. The first equation is y=2x+1. If we substitute x=2 and y=5, we get 5=2×2+1.
Verify First Equation: After performing the calculation, we find that 5=4+1, which simplifies to 5=5, which is true. Therefore, the point (2,5) satisfies the first equation.
Substitute and Check Second Equation: Next, we will substitute the point (2,5) into the second equation and check if it holds true. The second equation is x−y=−3. If we substitute x=2 and y=5, we get 2−5=−3.
Verify Second Equation: After performing the calculation, we find that 2−5=−3, which is also true. Therefore, the point (2,5) satisfies the second equation as well.
Solution to the System of Equations: Since the point (2,5) satisfies both equations, it is a solution to the system of equations.
