Statement 1: $\dfrac{ax + b}{cx + d} = \dfrac{p}{q}$.

⇒ q(cx + d) = p(ax + b)

This process is cross-multiplication.

Statement 2: ax + b = c becomes ax = c - b after transposition.

Which of the following options is correct?

1. Both the statements are true.

2. Both the statements are false.

3. Statement 1 is true, and statement 2 is false.

4. Statement 1 is false, and statement 2 is true.
