(7,3) because if you plug the 7 in for x and 3 in for y in both equations you get the right answer

817 10^-3
i believe (x,y) will turn into (y,-x), so your answer is (5,-2)
Answer:
x= 6 , y = 3
Step-by-step explanation:
x + 5y = 21
i am using trail and error method and i got the answer easily
the logic behind this is simple
the first equation is x + 5y = 21 so we can say that y will be 5 x 1 , 5 x 2 , 5 x 3 , 5 x 4
first i did 5 x 4 = 20
x + 5 x 4 = 21
x= 1 but the equation x + y = 1 + 4 = 5 which is not equal to 9
second i tried with 5 x 3 =15
and the equation will be
x + 5 x 3 = 21
6 + 15 = 21
this time the second equation became true
x + y = 9
6 + 3 = 9
the no of pounds of salsa = 6
no of pounds of tomato = 3
