Final answer:

To solve the equation expressed as Y = -1/3x - 4, we need to input different values of X to find the corresponding Y values, as it's a linear equation. For the given complex equations with multiple instances of Y, like Y = 140 + 0.9(Y – 0.3Y) + 400 + 800+600 -0.15Y, we simplify and combine like terms to isolate Y and solve for its value.

Step-by-step explanation:

To solve the equation Y = -1/3x - 4, you need to manipulate the equation to find specific values for Y when various X values are substituted. However, if we're looking at the provided equations similar to this format, such as Y = 140 + 0.9(Y – 0.3Y) + 400 + 800+600 -0.15Y, you start by simplifying the terms. For example:

Y = 140 + 0.9Y - 0.27Y + 1800 - 0.15Y

Here, you tighten up the Y terms:

Y = 1940 + 0.48Y

To isolate Y, you move all the Y terms to one side:


Y - 0.48Y = 19

Which simplifies to:

0.52Y = 1940

Finally, you divide both sides by 0.52 to find the value of Y:

Y = 3730
