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 $11$

$x=\frac{21}{11}$
