Final answer:
The value of y/2x-z when x = 4, y = 3, and z = 2 is -13/8.
Step-by-step explanation:
To evaluate y/2x-z when x = 4, y = 3, and z = 2, we substitute these values into the expression.
So, we have:
y/2x-z = 3/(2(4))-2 = 3/8-2 = 3/8-16/8 = (3-16)/8 = -13/8
Therefore, the value of y/2x-z when x = 4, y = 3, and z = 2 is -13/8.
