9(2x-1)=3(x+2)+3x
18x-9=3x+6+3x
18x-9=6x+6
18x-6x=6+9
12x=15
x=15/12
x=5/4
The equation 9 ( 2 x − 1 ) = 3 ( x + 2 ) + 3 x simplifies to x = 4 5 . This results in the final value of x being 1.25 after solving step by step. Through above calculations, we have effectively isolated the variable and arrived at the solution.
