Final answer:

To find the variable in an equation, follow a step-by-step process that involves identifying the unknown variable, identifying the known variables, choosing an appropriate equation(s) and solving for the unknown variable.

Step-by-step explanation:

In order to find the variable in an equation, you need to solve for it. Here's a step-by-step process:

  1. Identify the unknown variable.
  2. Identify the knowns, which are the other variables or values given in the equation.
  3. Choose an appropriate equation or set of equations that contain the unknown variable.
  4. Plug in the known values into the equation(s) and solve for the unknown variable.

For example, if you have the equation 4x + 3 = 11, the unknown variable is x. By subtracting 3 from both sides of the equation and then dividing both sides by 4, you can solve for x and find that x = 2.
