Algebra.Com's Answer #10154 by wuwei96815(245)![]() ![]() ![]() You can put this solution on YOUR website! You cannot solve this equation until you get all the variables on the same side.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "12-2a = -5a-9 First, add 2a to each side of the equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You get: 12-2a+2a = -5a-9+2a \n" ); document.write( "Simplified it becomes: 12 = -3a-9 Now, add 9 to each side. \n" ); document.write( "You get: 12+9 = -3a-9+9 \n" ); document.write( "Simplified it becomes: 21 = -3a \n" ); document.write( "21/-3 = a\r \n" ); document.write( "\n" ); document.write( "-7 = a\r \n" ); document.write( "\n" ); document.write( "You can check the correctness of this answer by substituting -7 for a in the original equation. \n" ); document.write( " |
