Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
