Simultaneous Equations.I know the basics of solving these, but I can't seem to get the following one right: Aloha Nui means Goodbye. #2 20051202 04:58:07
Re: Simultaneous Equations.The simplest way to get one of the equations to have an equal term to the other is to double the second one. Why did the vector cross the road? It wanted to be normal. #3 20051202 05:01:37
Re: Simultaneous Equations.Ah thankyou, I did not know of this method of making a pair of variables match. Aloha Nui means Goodbye. #4 20051202 05:04:43
Re: Simultaneous Equations.You're taking away the 10, but as it's already negative then it's equivalent to you adding 10. Why did the vector cross the road? It wanted to be normal. #5 20051202 05:18:48
Re: Simultaneous Equations.*slaps himself* Aloha Nui means Goodbye. #6 20051202 05:24:35
Re: Simultaneous Equations.Do we always use the method of multiplying one of the equations so that two of the variables match in value? Unless the coeffiecient of one of the variables is 1? Aloha Nui means Goodbye. #7 20051202 06:06:05
Re: Simultaneous Equations.What is the first step for the following simultaneous equation: Last edited by rickyoswaldiow (20051202 06:06:41) Aloha Nui means Goodbye. #8 20051202 06:08:35
Re: Simultaneous Equations.3x + 2y = 16 Aloha Nui means Goodbye. #9 20051202 08:46:30
Re: Simultaneous Equations.For that one, there's no way to get an equivalent term by changing just one of them (without involving fractions), so you need to change both. Why did the vector cross the road? It wanted to be normal.
