Add 7 to both sides. 4x=36. 36/4 is 9. So x=9.
C The game is not fair and they should stop playing
Your answer would be, There is No Real Solution to the equation.
Use the discriminant to solve for number of real roots.
Use the Quadratic Formula: a = 1, b = - 2, c = 9
D = b^2 - 4ac
Y = ax^2 + bx + c
D = ( - 2)^2 - 4 * 1 * 9
4 - 36
= - 32
Since the discriminant is a negative, Therefore, there is No Real Solution to the Equation.
