x=5/3\nx(6-1)=2x-5\n6x-1x=2x-5\n5x=2x-5\n5x-2x=5\n3x=5\nx=5/3\nu dont need to be a geek to do that, u just need to take about a week of algerbra 1

to solve for X, you have to separate X from everything else. in that problem 2X+3X=5, you would combine the 2X and 3X to get 5X. so the equation end up as 5X=5. from there, divide both side by 5. 5X/5=X and 5/5=1 so X=1.

are you simplifying? if so, here's your answer:\n\n(x^2-5x+6)(x^2-5x+5)=\nx^4-5x^3+5x^2-5x^3+25x^2-25x+6x^2-30x+30=\nx^4-10x^3+36x^2-55x+30\n\nwtf cranger, i got it right! what do you mean by CORRECT? check the bottom line

That's not an equation but it is the same as (6X+1)/X.\nIf you have y = 6+1/X then y-6 = 1/X and X= 1/(y-6); if y=0 then X= -1/6. X cannot equal 0, and y cannot equal 6, since you can't divide by 0.

x = 7 or 3\n\nTake the square root of each side of your equation, to get the following:\n\n| x-5 | = 2\n\nNotice I used absolute value signs, because either 2 or -2 squared will give us 4.\n\nSo, x-5 = 2 or x-5 = -2\n\nx-5 = 2 → x = 2+5 = 7\n\nx-5 = -2 → x = -2+5 = 3\n\nSo x=7 and x=3 are both solutions to your equation.\n\nHope that helped!\n\n~ ♥ ~

Starting with\nx^2 - 5x - 6.25 = 0\n\nMOVE the lone term to the right side of the equation.\n\nSo\n x^2 - 5x = 6.25\n\nTo comlete the square on the left:\nDIVIDE the coefficient of the x term (5) by two (2.5).  Then SQUARE it.\n\nADD \n 2.5^2 (which happens to be 6.25) to both sides\n\nNow\n x^2 - 5x + 6.25 = 6.25 + 6.25\n\nREWRITE the left which is now a perfect square\n (x-2.5)^2 = 12.5 (or 25/2)\n\nTAKE THE SQUARE ROOT OF BOTH SIDES\n x - 2.5 = +or- Square root of 12.5\n\nANSWER\n x = Sqrt 12.5 + 2.5   -or-\n x = 2.5 - Sqrt 12.5

First of all, solve both equations. So the first would be..\n\n3(2x+1)>5-2x \n     6x+3>5-2x (add 2x to both sides)\n         8x>2 (take 3 from both sides)\n           x>0.25 (divide both sides by 8)\n\nThe second would be..\n\n2x^2-7x+3>0\n4x^2-14x+6>0 (multiply both sides by 2)\n(2x-6)(2x-1)>0 (factorisation)\n \nReplacing > with =..\n\n2x-6=0,      2x-1=0\nx=3,                 x=0.5\n\nSo to satisfy both criteria, x must be greater than 0.25, greater than 0.5 and greater than 3. \n\nSo the answer is that x > 3.

2x - 7 = -4x - 1\n\nFirst, add 4x to both sides\n\n2x + 4x -7 = -1\n\nAdd like terms\n\n6x -7 = -1\n\nAdd 7 to both sides\n\n6x = 6\n\nDivide both sides by 6\n\nx = 1

Notice the first equation only involves x.\nx - 5 = 6\nAdd 5 to both sides\nx = 11\nNow replace x with 11 in the second equation\n3(11) - 2y = 5\n33 - 2y = 5\n-2y = 5 - 33\n-2y = -28\ny = -28/-2\ny = 14\nAnswer: (11,14)

(3x+5)(2x-3) = 6x^2 +x -15\n\n(x-1)(6x+5) = 6x^2-x-5\n\ntherefore you have \n\n6x^2+x-15 = 6x^2 -x -5\n\nsubtract 6x^2-x from both sides and you get\n\n2x-15 = -5\n\nadd 15 to both sides and you get\n\n2x = 10\ndivide both sides by 2\n\nx = 5
