My friend gave me this Alg 2 question, being a fairly smart lad I attacked it with full force!!! But I got amazingly confused, I don't even think it CAN be solved D: Anyway, thats why your here. To prove me wrong.

$105-40=65+H=$120
H=Hours Worked
($10/Hour)
Solve for H

(10 * 5) + 65 = 115
(10 * 6) + 65 = 125
so $10/hour the closest you will get is 5 over or 5 under it cant be 120 :? I hope you didnt see my first answer^^ .. and second reply :oops:

see I DO have brains :shock: and my math is useless.. my german is good i love the german language though so it would be better and I hate maths. I went to germany once for 6 months they have nice weather I kinda like it but I would LOVE to live in france!!! <3

I've taken algebra and have never seen such a poorly worded equation. Anyway, it can't be solved for because you can see immediately that something doesn't make sense...105-40 is 65. 65 is NOT equal to 120!

Take a pic of the textbook this is from if you're able to. I'd like to see this in the original context, since you might be butchering the problem. ;)

The way I understand it:

105 - 40 = 65

65 + H = 120

120 - 65 = H

H = 55

ADD: Derp. Talking about $10/H, you would just divide 55 by 10 to get 5.5 hours worked.

65 + H = 120
H = 120 - 65
H = 55

Am I missing something here? What's with all the confusion?

That was exactly my thought at first. It's still easy, you just have to account for H representing hours worked at $10/hour, instead of the money earned from working. In this case, H = 5.5 hours worked, for $55 total.

There you go. I would also like to see this in its original context, though. I think, as msbachman said, this problem was butchered.;)

What?

From what I see in the OP, it's an equation with three parts: A=B=C.

"A" here would be the 105 - 40.
"C" would be the $120.

Unless $120 = 105-40 by some miracle, this can't be solved.
