Algebra.Com's Answer #248129 by haileytucki(390)![]() ![]() You can put this solution on YOUR website! I believe this is what you are needing:\r \n" ); document.write( "\n" ); document.write( "2x-x+8=3x+3\r \n" ); document.write( "\n" ); document.write( "Since 2x and -x are like terms, add -x to 2x to get x. \n" ); document.write( "x+8=3x+3\r \n" ); document.write( "\n" ); document.write( "Since 3x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 3x from both sides. \n" ); document.write( "x+8-3x=3\r \n" ); document.write( "\n" ); document.write( "Since x and -3x are like terms, add -3x to x to get -2x. \n" ); document.write( "-2x+8=3\r \n" ); document.write( "\n" ); document.write( "Since 8 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 8 from both sides. \n" ); document.write( "-2x=-8+3\r \n" ); document.write( "\n" ); document.write( "Add 3 to -8 to get -5. \n" ); document.write( "-2x=-5\r \n" ); document.write( "\n" ); document.write( "Divide each term in the equation by -2. \n" ); document.write( "-(2x)/(-2)=-(5)/(-2)\r \n" ); document.write( "\n" ); document.write( "Simplify the left-hand side of the equation by canceling the common factors. \n" ); document.write( "x=-(5)/(-2)\r \n" ); document.write( "\n" ); document.write( "x= -25 \n" ); document.write( " |
