1 answer

To solve the equation \(-3x + 7 = 10\):

  1. Subtract 7 from both sides: \[ -3x = 10 - 7 \] \[ -3x = 3 \]

  2. Divide by -3: \[ x = \frac{3}{-3} = -1 \]

Now, to solve the equation \(3x - 9 = 0\):

  1. Add 9 to both sides: \[ 3x = 9 \]

  2. Divide by 3: \[ x = \frac{9}{3} = 3 \]

The solutions to the equations are \(x = -1\) and \(x = 3\).

The solution set is: \[ {-1, 3} \]

Therefore, the response is \({−1, 3}\).
