Answer:
a = 4 b = 5
Step-by-step explanation:
8a + 12b = 92......eqn 1
6a - 4b = 4......eqn 2
multiply eqn 2 by 3
18a - 12b = 12.....eqn 2
add eqn 1 and 2 to eliminate b
26a = 104
a = 4
put a = 4 into eqn 2
18(4) - 12b = 12
72 - 12b = 12
72 - 12 = 12b
60 = 12b
5 = b
The probability of drawing a club is 13/52. The probability of drawing a face card is 12/52. However, three of the clubs are also face cards, so there are only 22 of the 52 cards that are either clubs or face cards.

Answer:
b = -2ax
Step-by-step explanation:
Multiply both sides of the equation by -2a.
x = -b/(2a)
(-2a)x = b(-2a)/(-2a) = b
b = -2ax
