To subtract 1/2(z + 4) - 3(1/4z + 1), we need to distribute the –3 to both terms within the parentheses:
1/2(z + 4) - 3(1/4z + 1)
= 1/2(z) + 1/2(4) - 3(1/4z) - 3(1)
= 1/2z + 2/2 - 3/4z - 3
= 1/2z + 1 - 3/4z - 3
Now, we can combine the like terms:
(1/2z - 3/4z) + (1 - 3)
To combine fractions, they must have the same denominator. To obtain a common denominator, we multiply the numerator and denominator of the first fraction by 2 and multiply the numerator and denominator of the second fraction by 4:
(2/4z - 3/4z) + (4/4 - 12/4)
Simplifying fractions:
(-1/4z) + (-8/4)
= -1/4z - 2
Therefore, the final answer is -1/4z - 2.
