Below is the equation that represents the markers Janelle brought in for her math group.

x = the number of students in Janelle's math group.

3x + 5 = 23

Solve the equation to determine how many students are in Janelle's group?

1 answer

To solve the equation \( 3x + 5 = 23 \), we will follow these steps:

  1. Subtract 5 from both sides: \[ 3x + 5 - 5 = 23 - 5 \] This simplifies to: \[ 3x = 18 \]

  2. Divide both sides by 3: \[ \frac{3x}{3} = \frac{18}{3} \] This simplifies to: \[ x = 6 \]

Therefore, the number of students in Janelle's math group is 6.
