Answer:
1 pizza was left.
Step-by-step explanation:
If they didn't eat 1/2 of one pizza, 1/2 is left of one pizza.
If they didn't eat 2/4 of the other pizza, 2/4 is left of that other pizza/
2/4+1/2=2/4+2/4=1
Therefore, 1 pizza was left
So what you have to do first is get all the numbers without variables on one side, and y has to be by itself on the other.
you can do it like this:
3y+1=4y-6
-3y -3y
1=y-6
+6 +6
y=7
(you would add 6 b/c there is a minus sign next to it)
