7x+2y=19
7x+8y=13
Please solve it by Simultaneous method

x = 3 and y = -1

Step-by-step explanation:

7x + 2y = 19

7x + 8y = 13

0 - 6y = 6

y = -1

and putting the value of y in any equation

7x + 2(-1) = 19

7x = 21

x = 3

answer: .75 km

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
