wow this one is complicated ..
i can reach to certain point for solving it ,, you can do the rest :)
the eq. will be :
5/6x-1 * 1/5x+4 = 7/10x
5/ (6x-1)(5x+4) = 7/10x
5/(30x2+24x - 5x - 4 ) = 7/10x
50x = 7(30x2+24x - 5x - 4 )
50x = 210x2 + 168x - 35x - 28
50x = 210x2 + 133x - 28
210x2 + 83x - 28 = Zero
the u have to solve this equation to reach the two values of x :)
if someone knows please complete ...
6x - 4y
(-5 plus or minus the square root of 11) divided by 2 x = -0.8416876048223001 x = -4.1583123951777
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
2x + 10x - 6 = 12x - 6
8y-7x
6x - 4y
(-5 plus or minus the square root of 11) divided by 2 x = -0.8416876048223001 x = -4.1583123951777
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
10x - 5x + 5x = 10x
-10x = -50 Divide both sides by -10 remembering that a minus divided by a minus the quotient then becomes positive: x = 5 So: -10*5 = -50
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
2x + 10x - 6 = 12x - 6
-4x-6x = -20 -10x = -20 Divide both sides by -10 rembering that a minus divided into a minus the result is positive: x = 2
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2. There is, for example, no operator between 2 and 10X.
8y-7x
x2 + 10x + 21 = (x + 3)(x + 7)
