Answer 1

8(x)+4(y)+6 < 70
8(4) + 4(y) + 6 < 70
32 + 4(y) + 6 < 70
4y + 38 < 70
4y < 32
y < 8

8(4) + 4(8) + 6 = 70 :)

Answer 2

Alex can buy maximum of 8 drinks.

Explanation

Alex has $70, he buys 4 salads.

Let's "x" be the number of drinks he can buy.

Salad cost = $8 each

Drink cost = $4 each

Delivery charge = $6

So the equation is

4(8) + 4(x) + 6 = 70

32 + 4x + 6 = 70

38 + 4x =70

Subtracting 38 on both sides, we get

4x = 70 - 38

4x =32

Dividing both sides by 4, we get

x = 32/4

x = 8

Alex can buy maximum of 8 drinks.

Hope this will helpful.

Thank you.
