To solve for one variable in a linear equation, we need to isolate that variable. In this case, we want to isolate y.
First, we'll add y to both sides of the equation:
4x - y + y = 5 + y
Simplifying, we get:
4x = y + 5
Next, we can subtract 5 from both sides:
4x - 5 = y
This gives us our solution:
y = 4x - 5
Now we have an equation that tells us exactly what y is for any given value of x.
