Correct, but the final answer is $x=7y/9$ ("find the value of $x$ in terms of $y$").mathlearn said:
When we are asked to find the value of X in terms of Y, we are essentially being asked to express X in relation to Y. This means we need to manipulate the given equation or formula to isolate X on one side of the equation and express it in terms of Y on the other side.
To find the value of X in terms of Y, we need to follow the basic algebraic rules of solving equations. First, we need to identify which variable is X and which is Y. Then, we can use basic operations such as addition, subtraction, multiplication, and division to manipulate the equation and isolate X on one side. Once X is alone on one side, we can then express it in terms of Y on the other side.
Sure, let's say we have the equation 3X + 5 = 2Y. To find the value of X in terms of Y, we first need to isolate X. We can do this by subtracting 5 from both sides, which gives us 3X = 2Y - 5. Next, we divide both sides by 3, and we get X = (2Y - 5) / 3. This is the value of X in terms of Y.
Yes, it is possible to find the value of X in terms of Y even when there are multiple variables involved. The process is the same as before, we just need to identify which variable is X and use algebraic operations to isolate it on one side of the equation. The other variables can then be expressed in terms of Y.
Finding the value of X in terms of Y is important because it gives us a better understanding of the relationship between the variables in the equation. It also allows us to easily substitute values for Y and solve for X, which can be useful in real-world applications such as in physics and engineering. Additionally, it helps us simplify complex equations and make them more manageable to work with.
