Substitute in the value for x.
\n" ); document.write( "3(2y-4)-4y=12
\n" ); document.write( "6y-12-4y=12 Then, combine like terms
\n" ); document.write( "2y-12=12 Add 12 to both side of the equal sign to isoslate the variable y
\n" ); document.write( " +12 +12
\n" ); document.write( "2y=24 Divide by 2 to get the value of y
\n" ); document.write( "y=12. Substitute this value into the 2nd equation\r
\n" ); document.write( "\n" ); document.write( "x=2(12)-4
\n" ); document.write( "x=24-4
\n" ); document.write( "x=20.\r
\n" ); document.write( "\n" ); document.write( "Put it in ordered pairs for your answer
\n" ); document.write( "(20,12)
\n" ); document.write( " \n" ); document.write( "
\n" );
