Solve for x and y in the equations below
\(x^2- y^2= 4\)
x + y = 2
The correct answer is C. x = 2, y = 0
We are given the following system of equations:
1. \(x^2 - y^2 = 4\)
2. \(x + y = 2\)
We can solve this system using the method of substitution or elimination.
Let's solve using the method of substitution. From equation (2), we have \(y = 2 - x\). Substitute this value of \(y\) into equation (1):
\(x^2 - (2 - x)^2 = 4\)
Simplify the equation:
\(x^2 - (4 - 4x + x^2) = 4\)
Distribute the negative sign:
\(x^2 - 4 + 4x - x^2 = 4\)
Simplify further:
4x - 4 = 4
Now, solve for x:
4x = 8
x = 2
Now that we have x = 2, substitute it back into equation (2) to solve for y:
x + y = 2
2 + y = 2
y = 0
Therefore, the solutions are:
x = 2 and y = 0
