Where’s problem and um yea use photo math don’t waste your points on some math questions
That comes out to 3x^2 + 4x - 6 Answer
6x+1=2(x+3)+4x has no solution because if you simplify it you get 6x+1=6x+3 which can not have any solution, since anything you substitute for x will not give you a solution.
4x-1=4(x+3) also has no solution. if you simplify you get 4x-1=4x+3 so no value that you substitute for x will give you a solution
