Answer
$$x = 6$$
Work Step by Step
We have $$-5 + 3(x+5) = 2(3x-4)$$
Note we have two parenthesis so we are going to do each multiplications in order two eliminate them $$ -5 +3*(x) + 3*(5) = 2*(3x) + 2*(-4)$$
Doing each multiplication taking in count the signs law $$-5 +3x + 15 = 6x - 8$$
If we take all the numbers to the right side of the equality and all the $x$ terms to the left side $$3x - 6x = -8 +5 - 15$$
Simplifying $$-3x = -18$$
In order to solve the equation we are going to take that $-3$ which is multiplying to the other side dividing $$x = -18/-3$$
Finally taking in count the signs law we have that $$x = 6$$
