To solve the equation \( 4 - 2x = 10 \), follow these steps:
Step 1: Subtract 4 from both sides of the equation to isolate the term with \( x \). \[ 4 - 2x - 4 = 10 - 4 \] This simplifies to: \[ -2x = 6 \]
Step 2: Divide both sides of the equation by -2 to solve for \( x \). \[ \frac{-2x}{-2} = \frac{6}{-2} \] This simplifies to: \[ x = -3 \]
Step 3: Write the final solution. \[ x = -3 \]
Therefore, the solution to the equation \( 4 - 2x = 10 \) is \( x = -3 \).
