x = 200 is NOT a solution to the equation x ÷ 2 - 40 = 10 z = 20 is NOT a solution to the equation 5 × (z - 6) = 30

So?

>>10023971 This problem illustrates grouping like terms and dealing with subtraction in an equation. Solve x - 12 + 20 = 37. Replacing the -12 with a +(-12), we get x + (-12) + 20 = 37. Since addition is associative, the two like terms (the integers) may be combined. (12) + 20 = 8 The left side of the equation becomes

sage. i'm sick of this threads made of fail.

>>10024000 2x + 10 + (-10) = 20 + (-10) ==> 2x + (10 + (-10)) = 20 - 10 ==> 2x + 0 = 10 ==> 2x = 10.

>>10024000 American Math, lulz. No wonder China and India are getting stronger a tech countries.

>>10024031 >>10024031 The x is multiplied by 2, therefore we divide both sides by 2 to solve for x: 2 × (5 + 1 + 4) = 20 ==> 2 × 10 = 20 ==> 20 = 20 so our solution is correct.

>>10024020 lol where's your sage at?

ITT: Masters of Middle School Grade Algebra

>>10024049 Doesn't even match the fucking math problem. You can't do math right, you fuckup.

i should cap this thread and show it to someone saying "internet made me genious! 4chan made me genious!"

>>10024059 >>10024059 IT'S FUCKING 5. THE ANSWER IS 5

100 & 12. Wth is wrong with you people?

/a/ - mathematics

x - 12 + 20 = 37 x = 37 + 12 - 20 x = 29 .... or what?

>>10024106 Then: 2x = 10 ==> 2x ÷ 2 = 10 ÷ 2 ==> (2x)/2 = 5 ==> x = 5. Jesus, get it right.

>>10024133 The equation now becomes 2x + 10 = 20.

>/a/ - Mathematics

>>10024120 x is 13...

>>10024315 what's that supposed to mean? also ryuk cosplay = fail

>>10024351 >>10024315 I just lol'd really hard.

Are we back in elementary school math class? What the hell is this?

>>10024410 Solve : 3X+6Y= -6 5X-2Y=14

>>10024410

>>10024508 3x + 6y = -6 Divide this equation by 3 and rearrange for x, then use this x in your other equation. You will be able to get a value for y. Then you can finally use this value to get a value for x.

YOU SHOULD BE ABLE TO SOLVE THIS.

What does Death Note have to do with Algebra?

The answer is 5.

>>10024719 see >>10024734

solve for f'''(x) = 3x(sin(sin(sinx)))/2x(cos(sin(tanx)))

>>10024734 Yami actually got it right. Except his post didn't end in 5. So much for King of GETs.

>>10024508 3X+6Y= -6 5X-2Y=14 |*3 So we get 3X+6Y= -6 15x-6Y = 42 Which leads to 18x = 36 | / 18 x = 2

I want to see someone solve this
