Solution

First, let's replace the symbols according to the given conditions:

  • Replace '+' with '*'
  • Replace 'x' with '/'
  • Replace '÷' with '-'
  • Replace '-' with '+'

So, the expression 17 + 15 - 135 × 9 ÷ 70 becomes 17 * 15 + 135 / 9 - 70.

Now, let's solve this step by step:

  • Multiply 17 and 15, which equals 255.
  • Divide 135 by 9, which equals 15.
  • Subtract 70 from the result.

So, the expression becomes 255 + 15 - 70.

Finally, add 255 and 15, which equals 270, then subtract 70 from 270, which equals 200.

So, the value of the expression is 200. Therefore, the answer is (a) 200.
