Multiply the second equation by 2 so that its
6x+4y=-30
then subtract
6x+y=-39
6x+4y=-30
= -3y=-69
divide by -3 to isolate the y
then you get y=23
substitute the y value back into one of the equations to solve for x.
6x+23=-31
solve like you always do and you'll get your x
Congratulations, you solved a problem.

Answer:
im a investor
Step-by-step explanation:
C = 5p + 200
her folks are willing to spend 295....so c = 295....so sub in 295 for c and solve for p, the number of people that can attend
295 = 5p + 200
295 - 200 = 5p
95 = 5p
95/5 = p
19 = p <=== so 19 people can attend the party
