Answer 3

Solving the Equation

To solve the equation 2x + 9 = y, we can use basic algebraic principles to isolate the variable x.

First, we need to isolate x by getting it on one side of the equation. We can do this by subtracting 9 from both sides of the equation:

2x = y - 9

Now, to solve for x, we divide both sides of the equation by 2:

x = (y - 9) / 2

So, the solution to the equation 2x + 9 = y is x = (y - 9) / 2.
