Step-by-step explanation:
x=y+9
substitute
3(y+9)+8y=-6
3y+27+8y= -6
13y = -6 -27
13y= -33
y = -33/13
x = -33/13 + 9
Answer:
Step-by-step explanation:
JT = 19. 3(4) + 7
37 = CJ + JT
37 = 3x + 6 + 3x + 7
37 = 6x + 13
24 = 6x
X = 4
4x+6y=56 and y=4x can be used to determine the number of small cars rented and the number of large cars rented, where x represents number of small cars and y represents number of large cars.
Step-by-step explanation:
Number of people hold by small cars = 4
Number of people hold by large cars = 6
Let,
Number of small cars = x
Number of large cars = y
The students rented 4 times as many large cars as small cars,
y = 4x Eqn 1
which altogether can hold 56 people.
4x+6y=56 Eqn 2
4x+6y=56 and y=4x can be used to determine the number of small cars rented and the number of large cars rented, where x represents number of small cars and y represents number of large cars.
