I am having a hard time figuring out whether to add or subtract this system of equations (must solve by elimination).
\n" ); document.write( "5x+3y=8
\n" ); document.write( "2x-4y=-6
\n" ); document.write( "I multiplied the first equation by 4 and the second by 3 and I ended up with 20x+12y=32
\n" ); document.write( "6x-12y=-18
\n" ); document.write( "26x=14
\n" ); document.write( "x = 7/13
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "5x + 3y = 8
\n" ); document.write( "5(7/13) + 3y = 8
\n" ); document.write( "(35/13) + 3y = (104/13)
\n" ); document.write( "3y = (69/13)
\n" ); document.write( "y = 23/13
