Answer:
2x=14
Step-by-step explanation:
multiply the second equation by -1 and then when you add, the y's cancel out when you add and you are left with 1x=7. so multiply it by 2 and you get 14
5x - y = -3......this is just a matter of subbing in ur answer choices to see which one makes the equation true.
5x - y = -3.....subbing in (-2,-7)...x = -2 and y = -7
5(-2) - (-7) = -3
-10 + 7 = -3
-3 = -3 (correct)
so ur answer is : B. (-2,-7) <==
