x=-3

Step-by-step explanation:

3(4x + 1) - 4x + 3 = -18

Subtract 3 from both sides:

$3\left(4x+1\right)-4x+3-3=-18-3$

$3\left(4x+1\right)-4x=-21$

Expand:

$3\times4x+3\times 1-4x=-21$

12x+3-4x=-21

8x+3=-21

Subtract 3 from both sides:

8x+3-3=-21-3

8x=-24

Divide both sides by 8:

$\frac{8x}{8}=\frac{-24}{8}$

x=-3
