Given f(x) = 3x - 1 and g(x) = 2x - 3 for which value of x does g(x) = f(2)

How do you use the additive inverse to evaluate an expression that uses subtraction in a full sentence

Ineed ! the person who answers and shows their work on they got the answer first will be marked the !

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
