Hey guys! i need solving this equation! the equation is: 2x+3x=-11 x-y=12 the answer choices are: 7 and 19 5 and 17 -5 and 7 -7 and 5 i would really appreciate it if you could work it out and then explain why! you so much! god bless!

Ok so you have your two equations:
(1) 2x + 3y = -11 (I am assuming you meant 2x + 3y instead of 2x + 3x at least?)
(2) x - y = 12
x = y + 12

If we substitute equation (2) into equation (1) we get:
2(y + 12) + 3y = -11
2y + 24 + 3y = -11
5y = -35, therefor y = -7

If y = -7, from equation (2) we get:
x = -7 + 12 = 5
