First of all expand the brackets on the left.
We get: 9x - 24 = 4x + 6
Move everything to the left part
Get: 9x - 4x - 24 - 6 = 0
9x - 4x = 5x
Get: 5x - 24 - 6 = 0
Move the numerical part to the right
We get: 5x = 24 + 6
24 + 6 = 30
Get: 5x = 30
Divide the right and left parts by 5
We get: x = 6
It is answer to this question
