Solve y = x + 4 for x.
x = y − 4
x = y + 4
x = −y + 4
x = −y − 4

Option A.

Step-by-step explanation:

y = x + 4

As we know if we perform a similar operation on both the sides of the equation it doesn't affect the parent equation.

So we subtract 4 on both sides of the equation

y - 4 = (x + 4) - 4

x = y - 4

Therefore, option A. will be the answer.
