Final answer:
To solve the equation y = x + 4 for x, you need to isolate x on one side of the equation. Subtract 4 from both sides of the equation to get x = y - 4.
Step-by-step explanation:
To solve the equation y = x + 4 for x, we need to isolate x on one side of the equation. Here's how:
- Subtract 4 from both sides of the equation: y - 4 = x.
- So, x = y - 4.
That's the solution. x = y - 4.
