$12 x - 23$ $12x - 23$

$7 (3 x - 8) + 22 - 9 x$ $7(3x-8) + 22 - 9x$

First, use the distributive property (shown below) to simplify $7 (3 x - 8)$ $7(3x-8)$ :

Following this image, we know that:
$7 (3 x - 8) = (7 \cdot 3 x) + (7 \cdot - 8) = 21 x - 56$ $color(blue)(7(3x-8) = (7 * 3x) + (7 * -8) = 21x - 56)$

Put it back into the expression:
$21 x - 45 + 22 - 9 x$ $21x - 45 + 22 - 9x$

Combine like terms:
$12 x - 23$ $12x - 23$

Hope this helps!
