Answer: y = 40 + x
Step-by-step explanation:
y is the total number of minutes Emily studied for the exam. we already know that she studied for at least 40 minutes. But we also know that y does not equal 40. with the additional amount of time, x minutes, we can discern that y = 40 minutes plus the additional x minutes, which is simply y = 40 + x.
