You have the following equation:
3(2x - 5) + 4x = 5(2x + 3)
in order to solve for x, proceed as follow:
3(2x - 5) + 4x = 5(2x + 3) apply distributive property
6x - 15 + 4x = 10x + 3 simplify like terms
10x - 15 = 10x + 3 subtract 10x both sides
-15 = 3
the previous result is an incosistency, then, you ca conclude that the given equation does not have solution.
