Final answer:
The equation that represents the information is 3x + 5 = 23, where x represents the number of students in Janelle’s math group. To solve for x, subtract 5 from both sides of the equation, then divide both sides of the equation by 3.
Step-by-step explanation:
The equation that represents the information is 3x + 5 = 23, where x represents the number of students in Janelle’s math group.
To solve this equation, we need to isolate x by performing opposite operations. First, we subtract 5 from both sides of the equation:
3x + 5 - 5 = 23 - 5
This simplifies to:
3x = 18
Next, we divide both sides of the equation by 3 to solve for x:
3x/3 = 18/3
This simplifies to:
x = 6
Therefore, there are 6 students in Janelle’s math group.
