Answer
Does not have a solution.
Work Step by Step
We have $$3x + 1 -(x-5) = 2x - 4$$
As we see there is a minus sign before the parenthesis which is like a $-1$ multiplying it. So doing the multiplication in order to eliminate the parenthesis $$3x + 1 -1*(x) -1*(-5) = 2x - 4$$ $$3x + 1 -x +5 = 2x - 4$$
Taking $x$ terms to the left side of the equation and numbers to the right side $$3x - x - 2x = -4 - 1 - 5$$
Simplifying $$0 = -10$$
As we know 0 is not equal to 10 so our equation does not have a solution.
