Answer:

1. $7 for climbing the rock

Step-by-step explanation:

x is the number of laser tags

y is the number of times climbed the rock

a. 2x + 3y = 31

b. 4x + y  =27

lets find y

<u>Step 1</u>

4x + y = 27

y = 27 -4x

<u>step 2</u>

replace y with 27 - 4x in the a.

2x + 3( 27 - 4x) = 31

2x + 81 - 12x = 31

2x -12x = 31 -81

x = 5

y = 27 - 4(5)

y = 7
