Solving Linear Equations

ChanceMyHeart Says:

Mar 13, 2011 - Wow your youtube video really made me start understand linear equations. I pause your video first an then I try anwser it by myself I was way off. Infact no where near your answer. Then I watch your video an I get it now, infact you have open that side of my brain up so I have little more math inside my dull mind..LOL Thank you. Oh for real thank you so much.

Dec 2, 2011 - HOW DOES SHE GET NEGATIVE 36 WHEN SHE HAD NEGATIVE 15 SUBTRACTED BY A NEGATIVE 21 I THINK SHE MEANT POSITIVE 21?

Dec 4, 2011 - When you multiply two negative #s the answer is a positive #, but this is a situation of ADDING two negative #s(-15) + (-21) = -36One way to think of this as a situation where you borrow $15 from a friend today and a week later you borrow another $21 from the same friend ... you now owe the friend a total of $36. These concepts are covered in detail in our lesson 105 Rules For Integers & Absolute Value. Enter 105 in the "Search Math Lessons" box at mathmadesimpledotcom

Dec 22, 2011 - ex.28k-19=-2k+31:8k+2k=31+19?Im confused.

mathmadesimple Says:

Jan 2, 2012 - Work with equations by performing the same operation each side. The object is to get the letters on one side and numbers on the other.To get rid of the -2k on the right we add 2k on the right and 2k on the left8k - 19 +2k = -2k + 2k +3110k - 19 = 31 Add 19 to each side10k -19 +19 = 31 + 19 (the shortcut is to follow the rule: moving a term from one side of the equation to the other changes its sign)To Continue then10k = 50 divide each side by 10 to get k = 5

Jan 2, 2012 - k=5

Jan 4, 2012 - What if there were 2 variables? Ex: 2x+y= 3x-7.

mathmadesimple Says:

Jan 5, 2012 - When you have two variables in a linear equation you must have 2 different equations (a system of equations) to get a distinct solution for x and y. With a single equation you can use any value for one of the variables and get a corresponding value for the other."Solving Systems of Linear Equations" is lesson 205 at mathmadesimpledotcom

NaThAnPoNkIn Says:

Feb 29, 2012 - dont two negatives make a positive?!?! simple integers

mathmadesimple Says:

Mar 1, 2012 - Sometimes, it depends on what you are doing with the two negatives. If you are multiplying or dividing two negatives, the answer is positive.(-3)(-2) = + 6If you are adding two negative numbers the answer is negative (-3) + (-2) = - 5If you are subtracting two negative numbers, it depends,(-3) - (-4) becomes (-3) + (+4) = +1 and,(-4) - (-3) becomes (-4) + (+3) = -1Lesson 105 Rules for Integers and Absolute Value at mathmadesimpledotcom teaches this in detail.
