Solve the system of linear equations.
\n" ); document.write( "x/4 - y/11 = -9/44
\n" ); document.write( "x/6 - y/13 = -1/26\r
\n" ); document.write( "\n" ); document.write( "x/4 - y/11 = -9/44 (* 44 both sides)
\n" ); document.write( "x/6 - y/13 = -1/26 (* 26 both sides)\r
\n" ); document.write( "\n" ); document.write( "11x - 4y = -9
\n" ); document.write( "(13/3)x - 2y = -1 (26/6=13/3) (* 3 both sides)\r
\n" ); document.write( "\n" ); document.write( "11x - 4y = -9
\n" ); document.write( "13x - 6y = -3\r
\n" ); document.write( "\n" ); document.write( "11x - 4y = -9 (choosing this one and solving for y)
\n" ); document.write( "-4y = -11x - 9
\n" ); document.write( " 4y = 11x + 9
\n" ); document.write( " y = (11/4)x + (9/4)\r
\n" ); document.write( "\n" ); document.write( "13x - 6y = -3 (plugging our solved y into this)
\n" ); document.write( "13x - 6((11/4)x+(9/4)) = -3
\n" ); document.write( "13x - (66/4)x - (54/4) = -3
\n" ); document.write( "(52/4)x - (66/4)x = (-12/4) + (54/4) (52/4=13, -12/4=-3)
\n" ); document.write( "(-14/4)x = (42/4) (multiply both sides by 4)
\n" ); document.write( "-14x = 42
\n" ); document.write( "x=-3\r
\n" ); document.write( "\n" ); document.write( "11x - 4y = -9 (plug x=-3 into this and solve for y)
\n" ); document.write( "11(-3) - 4y = -9
