In a class of 32 students, 17 students like meat pies, 20 students like pizza and 5 students like both meat pies and pizza. How many students like ONLY pizza?

20 of the students ONLY like pizza.

Step-by-step explanation:

This is because when looking at the info given we know that 17 like meat pies (not ONLY pizza). Then, 5 students like BOTH meat pies AND pizza (not ONLY pizza). Only the 20 students enjoy ONLY pizza. Hope this helps and please mark brainliest!

x=6/7 and y=18/7

Step-by-step explanation:

If y = 3x and 2x + 4y = 12,

then substitute the value of y with 3x

2x + 4(3x) = 12

2x+12x=12

14x=12

x=12/14=6/7

y=3x=3*(6/7)=18/7
