I'm sorry, but it seems like the question provided contains some unrelated information at the end that does not pertain to solving the given simultaneous equations. To solve the simultaneous equations:
4x + 8y = 1
8x + 9y = 81
Here's how you can approach it:
1. Choose one of the equations and solve for one variable in terms of the other. Let's choose the first equation:
4x + 8y = 1
4x = 1 - 8y
x = (1 - 8y) / 4
2. Substitute this expression for x into the second equation and solve for y:
8((1 - 8y) / 4) + 9y = 81
Simplify the equation and solve for y.
3. Once you find the value of y, substitute it back into either of the original equations to find the corresponding value of x.
By following these steps, you can determine the values of x and y that satisfy both simultaneous equations. If you encounter any challenges or need further assistance with specific steps, feel free to ask for help!
