Answer for screen readers

The value of the variable $x$ is $2$.

Steps to Solve

  1. Identify the equation The equation given is $4 - x = 2$.

  2. Isolate the variable To solve for $x$, we need to get $x$ by itself. Start by subtracting 4 from both sides of the equation. $$ 4 - x - 4 = 2 - 4 $$ This simplifies to: $$ -x = -2 $$

  3. Solve for x Next, to eliminate the negative sign in front of $x$, multiply both sides of the equation by -1: $$ x = 2 $$

The value of the variable $x$ is $2$.

More Information

In algebra, isolating the variable is a fundamental skill. Here, we rearranged the equation step by step to find that $x$ equals 2, which follows from basic principles of equality.

Tips

  • Not properly isolating the variable: Sometimes, students forget to subtract or add the same value on both sides, leading to incorrect conclusions.
  • Skipping the negative sign: When dealing with subtraction, it’s easy to overlook the negative sign, which can result in the wrong answer.
