Solve the following equation

Question

12x + 40 = 304
A: x = 18
B: x = 22
C: x = 24
D: x = 25

Answer 1

To solve the equation \( 12x + 40 = 304 \), we start by isolating the term with \( x \).

1. Subtract 40 from both sides: \[ 12x + 40 - 40 = 304 - 40 \] \[ 12x = 264 \]

2. Now, divide both sides by 12: \[ x = \frac{264}{12} \]

3. Calculate \( \frac{264}{12} \): \[ x = 22 \]

So, the solution to the equation is \( x = 22 \).

The correct answer is: B: x = 22.
