Solve the system of equations by the method of substitution. x-2y= -1 x-5y= 2
\n" ); document.write( "x-2y= -1
\n" ); document.write( "x-5y= 2
\n" ); document.write( "---------
\n" ); document.write( "x = 2y - 1
\n" ); document.write( "x = 5y + 2
\n" ); document.write( "-----------
\n" ); document.write( "5y + 2 = 2y - 1
\n" ); document.write( "3y = -3
\n" ); document.write( "y = -1
\n" ); document.write( "----------
\n" ); document.write( "Sub for y to find x
\n" ); document.write( "
\n" ); document.write( "
\n" );
