You have
  x + x + 3 - 1*6 + 2 - 1 = 35 + 35 + (-1) + 4
  2x + 3 - 6 + 2 - 1 = 70 - 1 + 4
  2x - 3 + 2 - 1 = 69 + 4
  2x - 1 - 1 = 73
  2x - 2 = 73
  2x = 75
  x = 75/2
  x = 37.5
Check   37.5 + 37.5 + 3 - 1*6 + 2 - 1 = 35 + 35 - 1 + 4    (substitute the number 37.5 for x)
  75 + 3 - 6 + 2 - 1 = 70 - 1 + 4    (perform the first level of simplification)
  80 - 7 = 74 - 1    (combine positive numbers, combine negative numbers)
  73 = 73    (evaluate. Our answer checks.)

I'm assuming the * is a "times" or multiplication symbol so the left side of the equation can be reduced to 2X+2 The right side of the equation can be reduced to 70 +3 so 2x+2X7=73 so 2x+14=73 so 2x=73-14 so 2x=59 so x=59/2 so x=29.5
thanked the writer.

The order of operations requires multiplication be done first, followed by addition and subtraction left to right. You have performed the multiplication last, so have arrived at the wrong answer.
