Just plug in 32 (4 salads at $8 each) for x and solve for y.

8x + 4y + 6<=70
8x+4y+6=70
8x+4y=70-6
8x+4y=64
now we have given that x=4 number of salad and we need to find y=number of drinks so putt x=4 in last equation.
8(4)+4y=64
32+4y=64
4y=64-32
4y=32
y=32/4
y=8 is the number of drinks.
