(-2x^2 +5x-1)-(3x^2-4x-6)\n\nYou distribute the negative to each term in the second expression, then you add the two. - (3x^2-4x-6) negative to the 3x^2 is -3x^2, negative to the -4x is positive 4x, and negative to the -6 is positive 6. so then you have \n(-2x^2+5x-1) + (-3x^2+4x+6). -2x^2 and -3x^2 is -5x^2, 5x and + 4x is (+)9x, and -1 and 6 is 5. so you have \n-5x^2 + 9x + 5.\nI love doing these problems! :)

The equation just requires manipulation. First insert an equal sign for clarity and solve for an equality equation. \n2/3x(x+4)=4/5(x-5), multiply through, 2/3x+8/3=4/5x-4, rearrange, 4/5x-2/3x=8/3+12/3, note 12/3 equals 4, now factor and simplify using common denominators, x(12/15-10/15)=20/3, simplify, \nx(2/15)=20/3, divide both sides by 2/15 remembering to invert and multiply fractions, x=20/3*15/2, solve, x=50. Reinsert unequality sign, x<50 and try your answer in original equation. You'll find both sides will equal 36 when using 50 and then if you use less than fifty, the equation is true!!

2x+3 = 5\nsubtract 3 from both sides\n2x+3-3 = 5-3\n2x = 2\nDivide both sides by 2\nx=2/2\nx=1

I'm assuming you're new to algebra, so I'll do it the long way....\n\nSubtract 3 from both sides:\n\n1/2x + 3 - 3 = 9 - 3\n\n1/2x = 6\n\nMultiply both sides by 2\n\n1/2x * 2 = 6 * 2\n\nx = 3\n\nRemember, whatever you do to one side of the equation you need to do to the other side.

5 x (3 + 3) x 6  = 180\n\nEither the negative in front of your 5 is wrong, or you should've had a negative in front of 180.  In other words:\n\n-5 x (3 + 3) x 6  = -180\n\nHope that helped!\n\n~ ♥ ~

1/x + 1/6 =1/2\nEasiest thing is to multiply through by 6 to get rid of the fractions:\n\n6/X + 1 = 3 or 6/x = 2, therefore x=3.

2x - 5x^1/2 - 3 = 0\n2x-3= 5x^1/2\nsquare both sides:\n(2x-3)^2 = 25x\n4x^2 - 12x + 9 = 25x\n4x^2 -37x +9 =0\nx= ( 37 +- sqrt( 37^2 -4(4)(9) ) /2(4)\nx= ( 37 +- sqrt( 1225 ) /2(4)\nx= ( 37 +- 35 )/2(4)\nx=  72/8 or x= 2/8\nx= 9 or x = 1/4

x+1 / 2x = 2/3\nmultiply both sides by 2x; giving:\nx+1 = 4x/3\nmultiply both sides by 3; giving:\n3x +3 = 4x\nsubtract 3x from both sides; giving:\n3 = x\n____________\n9/2x-1 = 3/x\nmultiply both sides by 2x-1; giving:\n9 = (6x-3)/x\nmultiply both sides by x; giving\n9x = 6x-3\nsubtract 6x from both sides; giving:\n3x = -3\ndivide both sides by 3; giving:\nx = -1

2x-3>5\nor 2x-3+3>5+3 [adding 3 to both sides]\nor 2x>8\nor x>4 [dividing both sudes by 2]\n\n[I assume that '<_' sign means less than or equal to]\n5x+2<_32\nor 5x+2-2<_32-2 [adding -2 to both sides]\nor 5x<_30\nor x<_6 [dividing both sides by 5]\n\nFinally, combining both results 4<x<_6\n\nIf 'x' takes only integral values then x = 5,6
