Question
Answer:
lets do some subbing......(2,3)...x = 2 and y = 3

3x + 4y = 18
3(2) + 4(3) = 18
6 + 12 = 18
18 = 18.....so (2,3) is a solution for this equation

2x - 2y = 2
2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2....nope, so (2,3) is not a solution for this equation

B. The ordered pair (2,3) is not a solution to the system of equations...because for it to be a solution, it would have to satisfy both equations.
D. When (2,3) is substituted into the 2nd equation, it is false
F. When (2,3) is substituted into the 1st equation, it is true
