Answer:


x = 7 --- toppings


y = 27 ---- amount

Explanation:

Given


y \to\ amount


x \to\ topping

The first deal is:


y = 6 + 3x

The second is:


y = 20 + x

Required

The value of x and y [for which both deals are equal]

We have:


y = 6 + 3x


y = 20 + x

Equate both


y=y

So, we have:


6 + 3x = 20 + x

Collect like terms


3x - x = 20 - 6


2x =14

Divide by 2


x = 7

Substitute
x = 7 in
y = 20 + x


y = 20 + 7


y = 27
