There are an infinite number of equations that could have 9 and 7 as answers. Just one example (and an easy one) might be: x2 - 16x + 63 = 0 (x - 9) x (x - 7) = 0 (x - 9) = 0, x = 9 (x - 7) = 0, x = 7

The number of solutions an equation has depends on the nature of the equation. A linear equation typically has one solution, a quadratic equation can have two solutions, and a cubic equation can have three solutions. However, equations can also have no solution or an infinite number of solutions depending on the specific values and relationships within the equation. It is important to analyze the equation and its characteristics to determine the number of solutions accurately.
x2 - 12x + 35
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
