$color(brown)(x=4$

$9-2x=6x-23$

$:.-2x-6x=-23-9$

$-8x=-32$

multiply L.H.S and R.H.S. by $color(brown)(-1$

$:.8x=32$

$:.x=32/8$

$:.color(brown)(x=4$

substitute $color(brown)(x=4$

$:.9-2(color(brown)4)=6(color(brown)4)-23$

$:.9-8=24-23$

$:.1=1$

$x=4$

Given -

$9-2x=6x-23$

Take all the constant terms to right hand side and unknowns to the left hand side.

$-2x-6x=-23-9$
$-8x=-32$
$x=(-32)/(-8)=4$
$x=4$

How do you solve 9- 2x = 6x - 239- 2x = 6x - 23?
