Let's evaluate each question and determine the true statements.

Question 1: 10x = 90

  • If we divide both sides by 10, we get: \[ \frac{10x}{10} = \frac{90}{10} \] \[ x = 9 \]

The true statement is:

  • Divide both sides by 10; x = 9.

Question 2: x/13 = 39

  • If we multiply both sides by 13, we get: \[ 13 \cdot \frac{x}{13} = 39 \cdot 13 \] \[ x = 507 \]

The true statement is:

  • Multiply both sides by 13; x = 507.

Question 3: 14x = 56

  • If we divide both sides by 14, we get: \[ \frac{14x}{14} = \frac{56}{14} \] \[ x = 4 \]

The true statement is:

  • Divide both sides by 14; x = 4.

So, for each question:

  1. Divide both sides by 10; x = 9.
  2. Multiply both sides by 13; x = 507.
  3. Divide both sides by 14; x = 4.
