Answer:
8x + 3y = -47
Step-by-step explanation:
1. Use the y = mx + b form to find b:

2. Plug in b for the new equation:

3. Get rid of the denominators and simplify everything into standard form

Answer:
6 gallons
Step-by-step explanation:
You can find this using the ration method.
If, 8 gallons : 192 miles
x gallons : 144 miles
We must find the value of x, which is the number of gallons used to travel 144 miles.
Cross multiply the ratios.
192 x = 8 × 144
192 x = 1152
x = 1152 ÷ 192
x = 6
∴ It takes 6 gallons to travel 144 miles.
