To solve these equations, we can rewrite the equation in terms of x and substitute to the other.First equation:x+2y = 13and = 13/2 - x/2nd Equation:4x+8y=-9Substitute the first equation to the second equation:4x + 8(13/2 - x/2) = -9Solving the equation to cancel x. Therefore, the correct answer is C, not solutions.
