Simon:
cups of water --- x per day
cups of tea ------ x+1 per day
Kim:
cups of water --- y per day
cups of tea ----- 2y per day
".. drink a total of 140cups of tea and 90cups of water each day" ? each day?? , not reasonable!
did you mean for the 10 days?
If for 10 days:
10(x+y) = 90
x+y = 9
10(x+1) + 10(2y) = 140
x+1 + 2y = 14
x + 2y = 13
subtract them:
y = 4
then x = 5
state your conclusion
