Q. Which ordered pair is a solution of the equation?7x−2y=−5Choose 1 answer:(A) Only (1,5)(B) Only (−1,1)(C) Both (1,5) and (−1,1)(D) Neither
Check Solution 1,5: Step 1: Let's determine if the ordered pair 1,5 is a solution to the equation 7x−2y=−5. Substituting x=1 and y=5 into the equation yields 7⋅1−2⋅5=−5. Simplifying, we get 7−10=−3, which does not equal \$\(-5\)\). Therefore, \(1,5\) is not a solution.
Check Solution \((-1,1)\): Step \(2\): Now, let's check the second option \((-1,1)\). For this option, \(x=-1\) and \(y=1\). Substitute \(x=-1\) and \(y=1\) into the equation \(7x-2y=-5\). This gives us \(7*(-1)-2*1=-5\). Simplifying this, we get \(-7-2=-9\), which is not equal to \(-5\). So, the ordered pair \((-1,1)\) is not a solution of the equation.
Final Conclusion: Step \(3\): Since neither of the ordered pairs \((1,5)\) and \((-1,1)\) is a solution of the equation \(7x-2y=-5\), the correct answer is Neither.
