Since the amount of oil in the tank decreases constantly, we need to create a linear function. Using the base form, y = mx + b, we can replace -6 for m because volume decreases by 6 (or increases by -6) each hour, and +70 for b because we start off with 70 liters of oil. So we get y = -6x + 70, with x representing the number of hours, and y representing the volume of oil remaining.

4 - 7x = 1 - 6x <br>what is that

DanielleElmas [232]

Answer:

x = 3

Step-by-step explanation:

4 - 7x = 1 - 6x (Given)

4 - 1 - 7x = 1 - 1 - 6x (Subtraction Property of Equality)

3 - 7x = -6x (Simplify)

3 - 7x + 7x = -6x + 7x (Addition Property of Equality)

3 = x (Simplify)

x = 3 (Symmetric Property of Equality)
