Algebra.Com's Answer #377835 by racoon(5)![]() ![]() ![]() You can put this solution on YOUR website! since, in the question there is stated that f(x) = g(x), \n" ); document.write( "therefore, just equalise the two given equation: \n" ); document.write( "f(x) = -2x \n" ); document.write( "g(x) = 5x - 4\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "it will look like this; \n" ); document.write( "-2x = 5x -4\r \n" ); document.write( "\n" ); document.write( "group the same term on one side of the eq and numbers on the other side;\r \n" ); document.write( "\n" ); document.write( "-2x -5x = -4 \n" ); document.write( "* remember== each time a number@unknown is moved across the equal sign, the mathematical sign(+/-) become mirrored!!\r \n" ); document.write( "\n" ); document.write( "-7x = -4\r \n" ); document.write( "\n" ); document.write( "x = -4/-7\r \n" ); document.write( "\n" ); document.write( "since, negative divide by negative number produce positive number, erase the negative sign...\r \n" ); document.write( "\n" ); document.write( "x = 4/7 \n" ); document.write( " |
