Answer:

See below

Step-by-step explanation:

Part A

  • x + y = 90
  • y - x = 30

Part B

Substitute y in the first equation by y = x + 30 and solve for x:

  • x + x + 30 = 90
  • 2x = 60
  • x = 30 minutes on math

Part C

Let y = 70, then

  • 30 + 70 = 100 > 90

Elle spends 90 minutes total and 30 minutes on math. If she spends 70 minutes on drawing then total time will exceed her daily limit. She then needs to cut math time by 10 minutes or increase total time by 10 minutes.
