Solve for x in the following equation: 27/2x−5 + 1 =2. Explain why the abnswer is 16

1 answer

To solve for \( x \) in the equation

\[ \frac{27}{2x - 5} + 1 = 2, \]

we can start by isolating the fraction on one side.

  1. Subtract 1 from both sides: \[ \frac{27}{2x - 5} = 2 - 1, \] which simplifies to \[ \frac{27}{2x - 5} = 1. \]

  2. Multiply both sides by \( 2x - 5 \) (assuming \( 2x - 5 \neq 0 \)): \[ 27 = 1(2x - 5). \]

  3. Distribute on the right: \[ 27 = 2x - 5. \]

  4. Add 5 to both sides: \[ 27 + 5 = 2x, \] which simplifies to \[ 32 = 2x. \]

  5. Divide both sides by 2: \[ x = \frac{32}{2} = 16. \]

Thus, the solution is \( x = 16 \).

Explanation of why the answer is 16:

  • We correctly manipulated the equation to isolate \( x \).
  • We ensured each step followed algebraic principles, leading us step-by-step to the solution.
  • Substituting \( x = 16 \) back into the original equation verifies the solution:

\[ 2x - 5 = 2(16) - 5 = 32 - 5 = 27, \]

and

\[ \frac{27}{27} + 1 = 1 + 1 = 2, \] which matches the right-hand side of the original equation.

Thus, the value \( x = 16 \) satisfies the equation, confirming it is correct.
