Substitute x = 3 in any given equations. I will do in y = - x + 1

Therefore the answer is (3,-2)
Answer:
HOW ON THE WORLD WE SUPPOSED TO ANSWER DIS ?!?!?!
Step-by-step explanation:
Ashley can purchase 10 pizzas and Brian can purchase 12 so there would be nothing left on the cards
5/60=12
10/100=10
2(200+75) That would be one expression that can be used to find that.
5(5+x) = 6(6+4)
25+5x = 60
5x = 35
x = 7
-----------------
3(3+5) = 4(4+x)
24 = 16 + 4x
4x = 24-16
4x = 8
x = 2
