[tex]76(-2x-3)=19x+6[/tex]
First, lets expand the left side.
[tex]-152x-228=19x+6[/tex]
Add 152x on both sides.
[tex]-228=171x+6[/tex]
Subtract 6 on both sides.
[tex]-234=171x[/tex]
Divide both sides by 171.
[tex]-234/171=x[/tex]
Finally, x is equal to -234/171, which can be simplified to -26/19, or approximately 1.368.
