$x = - 24$ $color(green)(x = -24$

$\frac{2}{3} x + 9 = - 7$ $2/3x+9=-7$

Trasnposing $9$ $9$ to the right hand side, we get

$\frac{2}{3} x = - 7 - 9$ $2/3x = -7 - 9$

$\frac{2}{3} x = - 16$ $2/3x = - 16$

Multiplying both sides of the equation with 3, we get

$2/cancel(3)x times cancel(3) = - 16 times 3$

$2x = -48$

Dividing both sides by 2, we get

$(cancel(2)x) / cancel(2) = -48/2$

$color(green)(x = -24$
