document.write( "Question 743376: I am trying to solve the linear system of equations by graphing. the problem reads x/3+y/5=7/15 and the second part states x/4+3/8y=1/8. I know I must find a common denominator and put the problems into y=mx+b form. I am just having a hard time understanding them. \n" ); document.write( "
