Use elimination for number 2( multiply the bottom one by -1 the entire equation then add once you have the equation solve the equation to find x once you find x plug it in the top equation to ding y)(for substitution there should be a equation y= #x+or- # plug the part after the y into the other equation once you find x plug it in to the starter equation and go from there)(hope this helps)
<em>False</em> because what ever decisions the Supreme Court make is official so there is nothing to hide from and any ways if they did, later on they would tell everyone, so either way there would be no point of the making decisions behind closed doors.
