-5 x-10,4=0 -2 x^2+(x)/(2)=0

To solve the given system of equations, we can use the substitution method. Let's solve for x in the first equation: Adding 10.4 to both sides, we get: Dividing both sides by -5, we find: Now, substitute this value of x into the second equation: Substituting , we get:\(-2(-2.08)^2 + \frac{-2.08}{2} = 0\)Simplifying the equation, we find:\(2(4.3364) - 1.04 = 0\) Since the left-hand side of the equation is not equal to zero, there is no solution for the second equation. Therefore, the correct answer is , which means that there is no solution for x in the given system of equations.
