Weegy: What does y stand for?
User: it is an Unknown
User: What do you mean the police probably can?
Weegy: u simplify one equation to find a variable:
like this:
2x-4y=16
2x=16+4y
x=8+2y
and then you put that into the next equation, like this
3x-5y=19
3(8+2y)-5y=19
24+6y-5y=19
24+y=19
y = -5
tada
User: i do not understand
Weegy: simular to that answer is how you simplify it,,, hang on a second send me another message right after you get this one ok
User: simplify 2x^2 - 3x^2
Weegy: 0234
User: what
Weegy: Reduce to lowest terms 2x2 - 3x - 2 10 x - 3x2?
Answer
0234
(More) 8
(5y+3) - (4y+1)
= (5y + 3) + (-4y - 1)
= y + 2
