Solution:
I think the question should be as follow:
➙ 6x + 9 - ( 5x - 3 )
➙ 6x + 9 - 5 x + 3
➙ 6x - 5x + 9 + 3
➙ x + 12
➙ x = -12
Anyways I've also solved according to the provided question:
ㅤㅤㅤ➙ 6x + 9 (-5x - 3 )
ㅤㅤㅤ➙ 6x - 45x - 27
ㅤㅤㅤ➙ - 39 x - 27
Further, we can solve for x ;
ㅤㅤㅤ➙ - 39 x - 27 = 0
ㅤㅤㅤ➙ - 39 x = 0 + 27
ㅤㅤㅤ➙ x = - 27 / 39
