Yestarday isabel exercised 15 minutes longer than she exercised today. yesterday she exercised for 40 minutes. which equation can be used to find m the number of minutes Isabel exercised today?

40+15=x I think this is the answer sorry if its wrong

Let's use variables:

Y=amount of time Isabel exercised yesterday

T=amount of time Isabel exercised today

We know that:

L=40 and that L=T+15

Substituting we can say that:

40=T+15

Then, subtracting 15 from both sides:

40 (-15) = T+15 (-15)

T=25
