solve these systems of equations. they are:
\n" ); document.write( "-5x + 4y= 3
\n" ); document.write( "x= 2y - 15
\n" ); document.write( "-----
\n" ); document.write( "Use the 2nd equation.
\n" ); document.write( "Substitute for \"x\" in the 1st equation to get:
\n" ); document.write( "-5(2y-15) + 4y = 3
\n" ); document.write( "-10y+75 + 4y = 3
\n" ); document.write( "-6y = -72
\n" ); document.write( "y = 12
\n" ); document.write( "----
\n" ); document.write( "Now solve for \"x\"::
\n" ); document.write( "x = 2y-15
\n" ); document.write( "x = 2*12-15
\n" ); document.write( "x = 24-15
\n" ); document.write( "x = 9
\n" ); document.write( "------------
\n" ); document.write( "Cheers,
