To solve the system of equations given by
1. \( 100y + 50x = 100 \)
2. \( -25x + 50y = 50 \)
we can rewrite these equations in a more manageable form and check the provided answer choices.
First, let's simplify both equations.
1. Divide the first equation by 50:
\[
2y + x = 2 \quad \text{(Equation 1)}
\]
2. Divide the second equation by 25:
\[
-x + 2y = 2 \quad \text{(Equation 2)}
\]
Now we can rearrange Equation 1 to express \(x\) in terms of \(y\):
\[
x = 2 - 2y
\]
Next, substitute \(x\) into Equation 2:
\[
-(2 - 2y) + 2y = 2
\]
Distributing the negative:
\[
-2 + 2y + 2y = 2
\]
\[
4y - 2 = 2
\]
\[
4y = 4
\]
\[
y = 1
\]
Now substitute \(y = 1\) back into the equation for \(x\):
\[
x = 2 - 2(1) = 0
\]
So we have the solution:
\[
(x, y) = (0, 1)
\]
None of the other answer choices (-100, 100), (1, 100), (100, 1) are valid solutions.
Thus, the correct answer is:
\((0, 1)\)
