Linear equationsHello Forum, after i find the solution to this equation 5m+10=8m2, how do i check to make sure the answer is correct. Greatly appreciate any help! #2 20130713 02:12:27
Re: Linear equationsHi TryingMyBest50; Subtract 5m from both sides. Add 2 to both sides. Divide both sides by 3. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130713 02:24:55
Re: Linear equationsHi bobbym, i first need to say that math is not my subject. With that said, is that how i check that the solution is a true statement? #5 20130713 02:27:56
Re: Linear equationsYou check by substituting the 4 into the m. 5 x 4 = 20 and 8 x 4 = 32 20 + 10 = 30 and 32  2 = 30 Checked and you are done. In mathematics, you don't understand things.

Re: Linear equationsHi bob, i want to thank both you and bobbym for your feed back. So i just replace the answer with what ever letter is presented to check my that the sollution is correct, right? #9 20130713 02:46:52
Re: Linear equationsReplace the letter ( variable ) that you solved for and do the arithmetic correctly. Both sides should be the same. In mathematics, you don't understand things.

Re: Linear equationsVariable, i knew the letter had a name i just coudln't think of it. Thank you so much for your help! You guy's are great! Have a Blessed day! #12 20130713 05:25:09

Re: Linear equationsOh yes. But this is still weird for me: You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #17 20130713 05:52:20
Re: Linear equationsThat is true. I can remove one space and everything is fine.
Sounds cooling! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #18 20130713 10:34:11
Re: Linear equationsHi guy's it's me again. How do i turn this linear equation 4x+11=6x3 into an linear inequality? Would i write it like 4x<+11=6x<2, and the lesser sign is underlined? #19 20130713 11:30:44

Re: Linear equationsHi Bobbym, I need to change the linear equation 4x+11=6x3 into a linear inequality (using < or >). Can it be done? #21 20130714 01:39:10
Re: Linear equationsWhy couldn't you just replace the = with a < or a >? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #22 20130714 01:52:07
Re: Linear equationsok, so how would you solve the equation using < or >. #24 20130714 02:03:12
Re: Linear equationsI need to turn this linear equation 4x+11=6x3 into a linear inequality. #25 20130714 02:09:46
Re: Linear equations4x+11<6x3 or 4x+11>6x3 or 4x+11≤ 6x3 or 4x+11 ≥ 6x3 In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
