Use the method of substitution to solve the system of linear equations.
\n" ); document.write( "2x-y=8
\n" ); document.write( "9x-4y=36.
\n" ); document.write( "-----
\n" ); document.write( "Solve the 1st equation for \"y\":
\n" ); document.write( "y = 2x-8
\n" ); document.write( "---
\n" ); document.write( "Substitute for \"y\" and solve for \"x\":
\n" ); document.write( "9x - 4(2x-8) = 36
\n" ); document.write( "9x - 8x + 32 = 36
\n" ); document.write( "x = 4
\n" ); document.write( "----
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( " y = 2x-8
\n" ); document.write( "y = 2*4-8
\n" ); document.write( "y = 0
