[tex]3(x - 3) + 8x = 5(2x + 1)[/tex]
Expanding the terms,
[tex]3(x - 3) + 8x = 5(2x + 1) \\ 3x - 9 + 8x = 10x + 5[/tex]
Collecting like terms,
[tex]3x - 9 - 8x = 10x + 5 \\ 3x - 8x - 10x = 5 + 9[/tex]
Evaluating the terms,
[tex]3x - 8x - 10x = 5 + 9 \\ - 15x = 14[/tex]
Divide both sides by -15,
[tex] - 15x = 14 \\ x = - \frac{14}{15} [/tex]
