Your problem that you have gave out may be solved through the method of substitution.
\n" ); document.write( "Plug in the y from the second equation to the first equation.
\n" ); document.write( "x + 2(3x-14) = 14
\n" ); document.write( "x + 6x - 28 = 14 Distribution
\n" ); document.write( "7x - 28 = 14 Combine like terms
\n" ); document.write( "7x = 42 Addition Property of Equality
\n" ); document.write( "7x/7 = 42/7 Division Property of Equality
\n" ); document.write( "x = 6 Simplify\r
\n" ); document.write( "\n" ); document.write( "When we check our answers...\r
\n" ); document.write( "\n" ); document.write( "6 + 2(6(3)-14) = 14 Substitution
\n" ); document.write( "6 + 2(18-14) = 14 Simplify
\n" ); document.write( "6 + 2(4) = 14 Simplify
\n" ); document.write( "6 + 8 = 14 Simplify
\n" ); document.write( "14 = 14 Simplify
\n" ); document.write( "
\n" );
