(x - y) / 9 = m...multiply both sides by 9
x - y = 9m....subtract x from both sides
-y = 9m - x ...multiply both sides by -1 to make y positive
y = -9m + x....or y = x - 9m

Vikki [24]

Answer:

No student liked only Nokia

Step-by-step explanation:

The information can be illustrated as shown on the Venn diagram.

The number of students who liked only Nokia is x.

The sum of all regions in the Venn diagram should be 40.

We add all to get:

5 + 5 + 30 + x = 40

40 + x = 40

x = 40 - 40

x = 0

Therefore no one liked only Nokia
