Answer:
y = x/2 - z
Step-by-step explanation:
We'll "solve 2(y + z) = x for y in terms of x and z"
We wish to isolate y in 2(y + z) = x.
Start by dividing both sides by 2. We get (y + z) = x/2
Remove the parentheses: y + z = x/2
Subtract z from both sides: y = x/2 - z
This last result "makes y the subject"
