Answer:
number one is maybe 44 because -44x + 7y is 51 and number 2 is 30 because 30 - 4 is 26 I don't really know let me know if its wrong
Answer:
x = -2
y = 7
Step-by-step explanation:
-x + 7y = 51
-x - 4y = -26
=> -x + 7y = 51
-x - 4y = -26
=> -x + 7y = 51
x + 4y = 26
=> 7y = 51
4y = 26
=> 7y + 4y = 51 + 26
=> 11y = 77
=> y = 7
=> -x + 7(7) = 51
=> -x + 49 = 51
=> -x = 51 - 49
=> -x = 2
=> x = -2
