Plz erick, tyson, and lane together sold 90 tickets for the school banquet. erick sold 38 tickets, and tyson sold 24 tickets. how many tickets did lane sell?

Step-by-step explanation:

Okay, so let's represent the people as letters.

Erick= e

Tyson=t

Lane=l

They sold 90 tickets for the school banquet altogether. This means that e+t+l equals 90. Now since you know how much Erick and Tyson sold, this would mean you can replace your letters (variables) with numbers in your equation, like so:

e+t+l=90

38+24+l=90 (l remains a letter because we don't know how many he sold.)

Now add 38 and 24 to get 62.

62+l=90

To find l, we have to subtract 62 from 90.

   62+l=90

  -62    -62

   0+l= 28

   l=28           The answer is 28.

24+x=y
