Q. Which ordered pair is a solution of the equation?5x−2y=18Choose 1 answer:(A) Only (5,3)(B) Only (4,1)(C) Both (5,3) and (4,1)(D) Neither
Check Substitution (A): Substitute the x and y values from option (A) into the equation to check if it satisfies the equation.For the ordered pair (5,3), substitute x=5 and y=3 into the equation 5x−2y=18.5(5)−2(3)=25−6=19Check if the result equals 18.19=18
Result for Substitution A: Since the result from step 1 does not equal 18, option A is not a solution to the equation.
Check Substitution (B): Substitute the x and y values from option (B) into the equation to check if it satisfies the equation.For the ordered pair (4,1), substitute x=4 and y=1 into the equation 5x−2y=18.5(4)−2(1)=20−2=18Check if the result equals 18.18=18
Result for Substitution (B): Since the result from step 3 equals 18, option (B) is a solution to the equation.
Final Solution: Since option (A) is not a solution and option (B) is a solution, the correct answer is (B) Only (4,1).
