Jill is thinking of a number. Four more than three times the number is thirteen. What is the number?(1 point)

Question

Jill's number is
.

Answer 1

Let the number Jill is thinking of be represented by \( x \). According to the problem, we have the equation:

\[ 3x + 4 = 13 \]

To solve for \( x \), we first subtract 4 from both sides:

\[ 3x = 13 - 4 \] \[ 3x = 9 \]

Next, we divide both sides by 3:

\[ x = \frac{9}{3} \] \[ x = 3 \]

Therefore, Jill's number is \( 3 \).
