2 cases x 12 cans = 24 cans
24 cans x 54 oz per can = 1296 oz
1296 oz / 6 oz per serving = 216 guests served
-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
