Use substitution
x + x + 4 = 2
2x = -2, x = -1
Y = -1 + 4, y = 3
Solution: (-1, 3)

Answer:
24 blue cars
Step-by-step explanation:
Set up a proportion to solve this...
40/5 = x/3 (forty red cars is to five red cars as 'x' number of blue cars is to 3 blue cars)
Now solve by cross multiplying...
120 = 5x
24 = x
there is a 1/2 probability of getting heads on any one flip
since the first one landed on heads you have a 1/2 probability f getting a 2nd one
Probability = 1/2
