A two- word relative mode branch- type instruction is stored in memory at locations 207 and 208 (decimal). The branch is made to an address equivalent to decimal 195. Let the address field of the instruction (stored at address 208) be designated by X.

(a) Determine the value of X in decimal.

(b) Determine the value of X in binary, using 16 bits. (Note that the number is negative and must be in 2s complement notation. Why?)
