Splott solved it like this:

2x + 4 = –3x + 14
2x + 4 + 3x = –3x + 14 + 3x
5x + 4 = 14
5x + 4 + 4 = 14 + 4
5x = 18
5 x divided by 5 is equal to 18 divided by 5
x 	= 	18 over 5

Fizzle solved it like this:

2x + 4 = –3x + 14
2x + 4 – 2x = –3x + 14 – 2x
4 = 14 – 5x
4 – 14 = 14 – 5x – 14
–12 = –5x
–12 + 5 = –5x + 5
–7 = x

anonymous · Answer

x + 4 = –3x + 14
2x + 4 + 3x = –3x + 14 + 3x CORRECT
5x + 4 = 14  CORRECT
5x + 4 + 4 = 14 + 4 WRONG, he should have subtracted 4 both sides
5x = 18
5 x divided by 5 is equal to 18 divided by 5
x 	= 	18 over 5

anonymous · Answer

2x + 4 = –3x + 14
2x + 4 – 2x = –3x + 14 – 2x CORRECT
4 = 14 – 5x CORRECT
4 – 14 = 14 – 5x – 14 CORRECT
–12 = –5x WRONG, 4-14 = 10
–12 + 5 = –5x + 5 WEONG, he should gave divided -5 both sides
–7 = x

@Gregk which question are you reading :/

anonymous · Answer

oops i someone had a similar question

anonymous · Answer

Oh my .. lol

agent0smith · Answer

Both functions are quadratics, of degree 2. I've seen this question before, and it makes no more sense now than it did last time.

anonymous · Answer

I understand not one part of this question or how to even begin to answer it ..

agent0smith · Answer

I have a maths degree and I don't understand it either. I don't know what "operation" it's even referring to, and both functions have the same degree.

agent0smith · Answer

Where is this question from?

anonymous · Answer

My school .... lol

alekos · Answer

i think the "operation" refers to leg and arm movement and heat generated thereof

anonymous · Answer

Hmm , i think i got it .. I'll see what i can do . Thanks though !

alekos · Answer

what have you got? because i studied maths at uni and i reckon this a very ambiguous question

agent0smith · Answer

This is an awful question. It's hard to tell whether the degree refers to heat, or polynomial degree. In either case, both are essentially the same answer.

alekos · Answer

I agree. It's a stupid question to start with. Needs more info in order to obtain some sort of a sensible solution
