How can you find a numerical value for y, if there is no value given for x? More data needed.

To solve for y, you need to isolate the variable y on one side of the equation.

Given the equation y = x + 3, you can achieve this by subtracting 3 from both sides.

Subtracting 3 from both sides of the equation, you get:

y - 3 = x + 3 - 3

This simplifies to:

y - 3 = x

Finally, you can add 3 to both sides of the equation to isolate y:

y = x + 3
