Answer:
y = -5
Step-by-step explanation:
Isolate y:
-3x + 9y = -57
9y = -57 + 3x
y = (-57/9) + (3/9)x
Substitute for x:
y = (-57/9) + (3/9)(4)
y = (-57/9) + (12/9)
y = (-45/9)
y = -5
Answer:

Answer:
Step-by-step explanation:
<u>Equation for this case is:</u>
⇒ y = 6(x - 1) + 10 as Rs. 10 for the first km and Rs. 6 for the rest (x - 1) km
⇒ y = 6x - 6 + 10 simplifying
⇒ y = 6x + 4 final equation
<u>For x = 15 km we have total of:</u>
