The three Math Idol judges have been eliminating contestants all day! The number of one-step equations and two-step equations who have been eliminated today is equal to 1120. If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300, how many two-step equations auditioned today?
I tried this but I don't know if its right, someone help please (:

Assume that x = single step, y = double step operations.

x + y = 1120
3x - 2y = 1300

x = 1120 - y

3360-3y -2y = 1300
-5y = -2060
y = 412
x + 412 = 1120
x = 708

So you have 708 double step operations
and 412 single step operations.


This is what I had. Correct or nah?

Thanks. Was I right

fibonaccichick666 · Answer

looks good to me, so long as your computations are correct, you have the right steps

fibonaccichick666 · Answer

but, wait

fibonaccichick666 · Answer

remember what x= and y= you mixed them up

Oh okay...

fibonaccichick666 · Answer

why sad? you did the problem correctly, you just muffed up the end wording.  It happens to all of us

anonymous · Answer

Not sad, thank you for the help!(:

fibonaccichick666 · Answer

ok, good.  Don't be discouraged, if I was your teacher and I saw that work, I'd probably take off like 1/2 a pt for wording, but everything else was perfect.
