The expression without using absolute value is 2z - 11
Given the expression with absolute value expressed as:
lz-6l-lz-5l
Since absolute function can both be negative or positive, hence;
lz-6l-lz-5l = z - 6 - -(z - 5)
lz-6l-lz-5l = z-6-(-z+5)
lz-6l-lz-5l = z - 6 + z - 5
lz-6l-lz-5l = 2z - 11
Hence the expression without using absolute value is 2z - 11
