1 answer

Let's evaluate each question one by one:

Question 1: Solve the equation \( 10x = 90 \).

To solve for \( x \):

  • You can divide both sides by 10:

\[ x = \frac{90}{10} = 9 \]

The true statement is: Divide both sides by 10; x = 9.

Question 2: Solve the equation \( \frac{x}{13} = 39 \).

To solve for \( x \):

  • You can multiply both sides by 13:

\[ x = 39 \times 13 = 507 \]

The true statement is: Multiply both sides by 13; x = 507.

Question 3: Solve the equation \( 14x = 56 \).

To solve for \( x \):

  • You can divide both sides by 14:

\[ x = \frac{56}{14} = 4 \]

The true statement is: Divide both sides by 14; x = 4.

To summarize:

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