To solve the system of equations, we need to find the values of x and y that satisfy both equations.Given:
Step 1: Substitute the expression for y into the second equation.
Step 2: Square both sides of the equation to eliminate the square root.
Step 3: Simplify the equation.
Step 4: Solve for x.This equation is quite complex to solve directly. We can use numerical methods or graphing to approximate the solution.Using a graphing calculator or software, we find that the approximate solution is:
Step 5: Substitute the value of x back into the first equation to find y.
Therefore, the solution to the system of equations is:
To check the solution, substitute the values of x and y back into the original equations:
Substituting

:
The solution is correct.The given expression
does not seem to be related to the system of equations. It appears to be an independent expression.
