Q. Is (2,9)(2,9) a solution to this system of equations?\newliney=3x+3y = 3x + 3\newliney=4x+1y = 4x + 1\newlineChoices:\newline(A) yes\newline(B) no
  1. First Equation Check: We have the first equation: \newliney=3x+3y = 3x + 3 \newlineDoes the point (2,9)(2, 9) satisfy the first equation? \newliney=3x+3y = 3x + 3 \newline9=3(2)+39 = 3(2) + 3 \newline9=6+39 = 6 + 3 \newline9=99 = 9 \newlineYes, the point (2,9)(2, 9) satisfies the first equation.
  2. Second Equation Check: We have the second equation: \newliney=4x+1y = 4x + 1 \newlineDoes the point (2,9)(2, 9) satisfy the second equation? \newliney=4x+1y = 4x + 1 \newline9=4(2)+19 = 4(2) + 1 \newline9=8+19 = 8 + 1 \newline9=99 = 9 \newlineYes, the point (2,9)(2, 9) satisfies the second equation.
  3. Final Verification: We found: \newline(2,9)(2, 9) satisfies the equation y=3x+3y = 3x + 3. \newline(2,9)(2, 9) satisfies the equation y=4x+1y = 4x + 1. \newlineIs (2,9)(2,9) a solution to the system of equations? \newliney=3x+3y = 3x + 3 \newliney=4x+1y = 4x + 1 \newlineBoth equations cannot be true simultaneously for the same point because they represent two different lines. There is a mistake in our previous steps. We need to check our calculations again.
