$3(14 - 5x) = 16 - 12x$

Distribute 3 throught the parentheses

$42 - 15x = 16-12x$

Move the variable to the left-hand side and change its sign

$42 - 15x + 12x = 16$

Move the constant to the right-hand side and change its sign

$- 15x+12x=16 - 42$

Collect like terms

$- 3x = - 26$

Divide both sides of the equation by -3

$\boxed{x = \frac{26}{3} }$
