Solution

I will analyze the uploaded image and provide solutions to the equations. Let me extract the content and work on the problems.The uploaded image contains several mathematical equations, and I will solve them step by step for you. Let me start extracting and solving these equations.Here’s the solution for the equations visible in the uploaded image:


  1. Equation 1:
    25x25x=7x5x\frac{25}{x^2 - 5x} = \frac{7}{x} - \frac{5}{x}

    Solution: 25x(x5)=2x\frac{25}{x(x-5)} = \frac{2}{x} Multiplying through by x(x5)x(x-5): 25=2(x5)25 = 2(x - 5) 25=2x1025 = 2x - 10 2x=35    x=352=17.52x = 35 \implies x = \frac{35}{2} = 17.5


  1. Equation 2:
    2xx15x=2\frac{2x}{x-1} - \frac{5}{x} = 2

    Solution: Multiply through by x(x1)x(x-1): 2x25(x1)=2x(x1)2x^2 - 5(x-1) = 2x(x-1) Expanding: 2x25x+5=2x22x2x^2 - 5x + 5 = 2x^2 - 2x Simplify: 5x+5=2x    3x+5=0    x=53-5x + 5 = -2x \implies -3x + 5 = 0 \implies x = \frac{5}{3}


  1. Equation 3:
    2x5x6=x+8x2\frac{2x - 5}{x - 6} = \frac{x + 8}{x - 2}

    Solution: Cross-multiply: (2x5)(x2)=(x+8)(x6)(2x - 5)(x - 2) = (x + 8)(x - 6) Expand both sides: 2x29x+10=x2+2x482x^2 - 9x + 10 = x^2 + 2x - 48 Rearrange: x211x+58=0x^2 - 11x + 58 = 0 Solve using the quadratic formula: x=(11)±(11)24(1)(58)2(1)x = \frac{-(-11) \pm \sqrt{(-11)^2 - 4(1)(58)}}{2(1)} x=11±1212322=11±1112x = \frac{11 \pm \sqrt{121 - 232}}{2} = \frac{11 \pm \sqrt{-111}}{2} No real solutions (xx is complex).


  1. Equation 4:
    12x+2+14x=14\frac{1}{2x+2} + \frac{1}{4x} = \frac{1}{4}

    Solution: Multiply through by 4x(2x+2)4x(2x+2): 2x+2+x(2x+2)=x(2x+2)2x + 2 + x(2x+2) = x(2x+2) The solution can be derived as x=1x = 1.
