First, distribute the fractions:
1/2(z+4) - 3(1/4z+1)
= 1/2 * z + 1/2 * 4 - 3 * 1/4 * z - 3 * 1
= 1/2z + 2/2 - 3/4z - 3
= 1/2z + 1 - 3/4z - 3
Next, combine like terms by combining the coefficients of z:
= (1/2z - 3/4z) + (1 - 3)
= (2/4z - 3/4z) - 2
= -1/4z - 2
The final form is -1/4z - 2.
subtract 1/2(z+4)-3(1/4z+1). use fractions in final form
