Answer:
see below
Step-by-step explanation:
x- time spent on math and y- time spent on dancing
Total time 80 minutes a day
<u />
<u>Part A: </u>
The equations:
x+y= 80
y-x= 20
<u>Part B: </u>
Using the pair of equations above, when adding them up we get:
2y= 100 ⇒ y= 50 min dancing
and
x= 80- 50 =30 min math
<u>Part C: </u>
if y= 60 and x= 60 -20= 40
then total time spent would be 100 min, which is more than 80 minutes
So answer is no, it is not possible
