Solve for x. 12 - x/9 = 11 (1 point)

3 answers

To solve the equation \( 12 - \frac{x}{9} = 11 \), follow these steps:

  1. Subtract 12 from both sides of the equation:

    \[ -\frac{x}{9} = 11 - 12 \]

    \[ -\frac{x}{9} = -1 \]

  2. Multiply both sides by -1:

    \[ \frac{x}{9} = 1 \]

  3. Multiply both sides by 9 to solve for \( x \):

    \[ x = 9 \]

Thus, the solution is \( x = 9 \).

Solve for X. -20 = -5 + 3x

To solve the equation \(-20 = -5 + 3x\), follow these steps:

  1. Add 5 to both sides of the equation:

    \[ -20 + 5 = 3x \]

    \[ -15 = 3x \]

  2. Divide both sides by 3 to isolate \(x\):

    \[ x = \frac{-15}{3} \]

    \[ x = -5 \]

Thus, the solution is \( x = -5 \).
