Question

Two classroom have a total of 45 people in them. the first class is a math class with 5 more students than the science class. How many are in each class

Answer 1

Answer:

$x=25$

Step-by-step explanation:

Set an equation:

$x + x -5 = 45$

Combine like terms:

$2x - 5 = 45$

Add 5 to both sides:

$2x = 50$

Divide both sides by 2:

$\frac{2x}{2} = \frac{50}{2}$

$x = 25$
