Question

Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two. Hisheating budget for the winter is $600. (7.1)a. Write a linear equation that describes the problem.

Answer 1

Answer:

The linear equation can be written as

$3x+y-(x+y)= 600$

Step-by-step explanation:

Given that "Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two"

And his heating budget for the winter is $600

To find a linear equation that describes the problem:

Let the cords of wood be x and let sing natural gas be y

So that the combination of the cords of wood and sing natural gas is x+y

Now the linear equation can be written as

$3x+y-(x+y)= 600$
