Which statements are true the ordered pair (1, 2) and the system of equations? y=−2x+47x−2y=3 HELP ASAP! WILL GIVE BRAINLIEST
2 answers:
When (1,2) is substituted into the first equation, the equation is true. The ordered pair (1,2) is a solution to the system of linear equations. When (1,2) is substituted into the second equation, the equation is true.
To solve, plug the value of the variables in each equation in the system (1,2) means x = 1 and y = 2 y = -2x + 4 2 = -2(1) + 4 2 = -2 + 4 2 = 2 the ordered pair is a solution to the first equation 7x - 2y = 3 7(1) - 2(2) = 3 7 - 4 = 3 3 = 3 the ordered pair is a solution for the second equation Because the ordered pair is a solution for BOTH equations in the system, it is a solution to the system. Therefore, the correct answers are: "When (1,2) is substituted into the first equation, the equation is true." "The ordered pair (1,2) is a solution to the system of linear equations." "When (1,2) is substituted into the second equation, the equation is true." Hope this helps!
