Yes, I can solve them.\n\nLike any other fractions, find a common denominator.  Though with (a) you can just multiply everything by 7x and simplify the equation to:\n\n21 + 1 = -14x\n\nYou can do the same with (c).  With (b) it's a little more complicated, and you have to find the common denominator of x and (x + 6).  I'll leave that for you.

Okay, here we go:\n\n1) -2x-10-7 = 3x+2x-10\n    -2x-17 = 5x - 10\n    -2x -5x = -10+17\n    -7x = 7\n       x = -1\n\n2) 12x+6-6x = 5x-10-5x\n     6x+6 = -10\n     6x = -10 - 6\n     6x = -16\n     x = -8/3\n\n3) 30x-5-10x+5 = 4x+40-4x\n    20x = 40\n    x =2\n\n4) -24+6x+12 = 3x-x+4\n    6x-12 = 2x+4\n    6x-2x = 4+12\n    4x=16\n     x = 4\n\nSee? It's quite easy.

4) is eliminated because x>-5\n\n2-3x>-1\n-3x>-3\nx<3\n\nThis eliminates none, and the other eliminates only 4.\n\n4 is your answer.\n\nHope this helps.

x = 3/(x-2)\n\n=> x(x-2) = 3\n=> x^2 - 2x = 3\n=> x^2 - 2x - 3 = 0\n=> (x-3) (x+1) = 0\n\nEither x-3 = 0 => x=3\nOr x+1 = 0 => x=-1

I hope you are trying to say x+2 = (2/3)(2x-1)..if it is correct then\n\n3(x+2) = 2(2x-1) --> 3x+6 = 4x - 2 --> 6+2 = 4x-3x --> 8 = x
