document.write( "the steps i took to begin this problem was substitue the wording for the first, second and third with x,y,z. and wrote x + y+ z = 161, then i wrote y = 7 + x for \"the second # is 7 more than the first # \"; and z = 5x for \" the third # is 5 times the first #\". after that i am stuck on how to finish and solve the problem. am i on the right track to start? \n" );
