The sum of two numbers is 13 the difference of the same two numbers is -7 find the numbers

x + y = 13

x - y = -7

To solve, we can use the addition property:

2x = 6

x = 3

y = 10

{3, 10}

answer: i think it is (1,-2)

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
