3. Which of the following equations would not have a solution that is the same as the solution to the system
shown below?
(1) 3x +2y=6
(3) 5y = -9
(2) 4x+6y=2
(4) 2x - 2y=5
x-y=5. 2x+3y=1

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
