Answer:
25
Step-by-step explanation:
Because 100 25+25+25+25 or 25/1/4
From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
Y doesn't change so it stays 3.
x will be 0, because the average of 0 and -2 is -1
They split it 50/50 that's the answer

Multiply -6 by -5.
Note: Whenever you multiply or divide a negative number by another negative number, it automatically becomes a positive number.
