3x and -10x are like terms. Combine them to get -7x. Notice how 3 + (-10) = 3 - 10 = -7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So that's why 3x - 10x = -7x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in the end, the final answer is -7x + 12
\n" ); document.write( "
\n" );
