algebra

Some Rules: Whatever you do to one side, you do to the other. KEY: BE PATIENT To take a number away, you need to do the opposite operation. Q: 2x+8+x=x+16 variable number (x) 3x+8=x+16 3x-x+8=x-x+16 2x+8=16 2x+8-8=16-__8__ 2x 8 algebra is a slow process so take your time and concentrate** -=- 2 2 3x + 4x = 5y + 2x 3x + 4x would be 7x = 5y + 2x subtract 2x form both sides 7x - 2x = 5y + 2x - 2x TRY THIS: x+x+2x=1+x=11 5x = 5y x=y

Posted by: Coconut Cracker To do algebra you have to take it step by step

I will use the question: n+2n+3n=120

Step 1: In this question, you first have to add all the unknowns together. So that means you add n+2n+3n and you get 6n Step 2: Next you divide 6 by n so 6 ÷ N = 1n. just a n also means 1n. Step 3: Now you have n = 120 but don't forget what you do to one side you have to do to the other. So n=120 ÷ 6 Step 4: Now you figure out what 120 divided by 6 is and you get 20, so n = 20

Note, the variable can be any letter

I have a strategy for dividing, multiplying, adding and subtracting with algebraic equations ..... FOLLOW THIS PROCEDURE I will use the equation 2n+n-10=24 First we add so. . we add 2n and n to get 3n Then the equation becomes 3n-10=24 Now the equation say 3n-10 we need to do the opposite operation so since we subtracted before we need to add now so the equation becomes 3n-10+10=24 and there is a rule that says what you do on one side of the equal sign you have to do with the other and now the equation looks like 3n-10+10=24+10 so the equation is 3n=35 Now we divide. there is a few ways to divide but the method I like to use looks like this.... 3n/3 so you cross out the threes so now we have to do the same thing on the other side 24/3 = 8 so in the end we have n=8 And now we need to verify:) so we re-write the equation 2n+n-10=24 then we fill the spots that have n with the number we think it is 2(8)+8-10= 24 so we do the equation and if both the sides end up with the same number our answer is right So 2x8+8 is 24 and the other side is 24 so 24=24 We have the right answer !
