$x = - 3$ $color(blue)(x=-3$

$3 \cdot (2 x + 1) = 2 x - 9$ $3 * (2x+1) = 2x-9$

$3 \cdot (2 x) + 3 \cdot (1) = 2 x - 9$ $3 * (2x) + 3 * (1) = 2x-9$

$6 x + 3 = 2 x - 9$ $6x + 3 = 2x-9$

$6 x - 2 x = - 9 - 3$ $6x -2x= -9-3$

$4 x = - 12$ $4x= -12$

$x = - \frac{12}{4}$ $x=-12/4$

$x = - 3$ $color(blue)(x=-3$

How do you solve this linear equation 3(2x+1)=2x−9 3(2x + 1) = 2x - 9?
