You can put this solution on YOUR website!
let the unknown number be \"x\"\r
\n" ); document.write( "\n" ); document.write( "the mathematical expression for \"five times the difference between a number and two...\" would be:\r
\n" ); document.write( "\n" ); document.write( "5(x-2)\r
\n" ); document.write( "\n" ); document.write( "the mathematical expression for \"...is the same as four times the number\" would be:\r
\n" ); document.write( "\n" ); document.write( " = 4x\r
\n" ); document.write( "\n" ); document.write( "so combining the expressions would lead us to:\r
\n" ); document.write( "\n" ); document.write( "5(x-2) = 4x\r
\n" ); document.write( "\n" ); document.write( "solving for \"x\" :\r
\n" ); document.write( "\n" ); document.write( "5x - 10 = 4x Distribute 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5x - 4x = 10 Combining like terms\r
\n" ); document.write( "\n" ); document.write( "x = 10 Answer!\r
\n" ); document.write( "\n" ); document.write( "Checking: \r
\n" ); document.write( "\n" ); document.write( "5 ( 10 - 2 ) = 4 (10) Substitute the Answer\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5 ( 8 ) = 40 \r
\n" ); document.write( "\n" ); document.write( "40 = 40 Correct!\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
