Do these three problems need help!!

3(x-8)-5=9(x+2)+1

2(x+2)+x=5+4(x-2)

5x-(3x-3)=2x+3(x+4)

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

Which number line represents the solution set for the inequality -1/2x> 24?
