What is the solution of 2x - 7 = x / 2 - 1

1 answer

To solve the equation \( 2x - 7 = \frac{x}{2} - 1 \), follow these steps:

  1. Start by eliminating the fraction. To do this, multiply every term by 2 (the denominator):

\[ 2(2x - 7) = 2\left(\frac{x}{2} - 1\right) \]

This simplifies to:

\[ 4x - 14 = x - 2 \]

  1. Next, isolate \(x\) by getting all \(x\) terms on one side and constant terms on the other side. Subtract \(x\) from both sides:

\[ 4x - x - 14 = -2 \]

This simplifies to:

\[ 3x - 14 = -2 \]

  1. Now, add 14 to both sides:

\[ 3x = 12 \]

  1. Finally, divide both sides by 3 to solve for \(x\):

\[ x = 4 \]

Thus, the solution to the equation \( 2x - 7 = \frac{x}{2} - 1 \) is

\[ \boxed{4} \]
