Question:
Please Help, I dont know where to start?
1)
     multiply by (x+2)(x-8)
         5 (x - 8) + 2 = -4 ( x + 2)
         5x - 40 + 2 = - 4x - 8
                     9x = 30 => x = 10/3
     
2)
    
      
        4x = 5(x+5) => 4x = 5x + 25 => x = -25
     
3)
     quadratic both sides
         2x + 10 = 4x
                10 = 2x => x = 5
