Question

How many solutions does the equation -2y+(4-y)=12-5y have?

Answer 1

Well, simplify it. What do you get?

Answer 2

the same thing on both sides, -5y+12=12-5y. So would it be no solution?

Answer 3

-2y + 4 - y = 12 - 5y
Combining and gathering y terms on one side and then evaluating gives you:
-3y + 4 = 12 - 5y
-3y + 5y = 12 - 4
2y = 8
y = 4

So, one solution.

Answer 4

Unless, what you meant to type was -2y + 3(4-y). :)

Answer 5

oh, yeah.. sorry about that! haha. X)
