Let's solve this by substitution.
y is given by the 2nd eqn as y = (1/3)x + 7. Subst. (1/3)x + 7 into the first eqn as a replacement for y: x + 9( (1/3)x + 7) = 3.
clear out fractions by mult. all 3 terms by 3: 3x + 9x + 63 = 3
Combine like terms: 12x = -60. Then x = -5
Find y by subst. -5 for x in the 2nd equation: y = (1/3)(-5) + 7
= -5/3 + 35/3 = 30/3 = 10.
Thus, the solution (x,y) of this system is (-5,10).

Answer:
12:40 is the anwser
Step-by-step explanation:
If his flight leaves at 3:15 and it takes and hour and 35 minutes to gett there than you would have to subtract 1 hour and 35 minutes from 3:15 so
3:15 minus 1 hour is 2:15
2:15 minus 35 minutes is 1:40
so now he wants to be and hour and 35 minutes earlier so the anwser would be
2:15 minus 1 hour is 1:15
1:15 minus 35 minutes is 12:40
