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

4. Gregk

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

5. Gregk

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 :/

7. Gregk

oops i someone had a similar question

8. LaynaMae

Oh my .. lol

9. agent0smith

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.

10. LaynaMae

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

11. agent0smith

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.

12. agent0smith

Where is this question from?

13. LaynaMae

My school .... lol

@agent0smith

16. alekos

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

17. LaynaMae

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

18. alekos

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

19. agent0smith

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.
