Remove parentheses $(-a)=-a$
$15x-20=6x-(x+2)-x+3$
Group like terms
$15x-20=6x-x-(x+2)+3$
Add similar elements: $ 6x-x=5x$
$15x-20=5x-(x+2)+3$
Expand $5x-(x+2)+3:{\quad}4x+1$
$15x-20=4x+1$
Move $ 20 $to the right side
$15x=4x+21$
Move $ 4x $to the left side
$11x=21$
Divide both sides by $11$
$x=\frac{21}{11}$
