Question

Describe a real- world situation that can be modeled by the equation 15x = 135. Solve the equation and explain what the solution means in this situation

Answer 1

A situation could be for example if you wanted to buy a large amount of {something} and you had $135. To find out how many you would be able to buy, you would solve the equation.

$15x = 135 \\ \frac{15x}{15} = \frac{135}{15} \\ x = 9$

So 9 would be the amount of {something} that you could buy.
