Algebra.Com's Answer #486310 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! 3(x + 2) – 4x = 3 \n" ); document.write( "Multiply (x + 2) by 3 \n" ); document.write( "3x + 6 - 4x = 3 \n" ); document.write( "Collect like terms remembering to \n" ); document.write( "change signs as you cross the = sign. \n" ); document.write( "3x - 4x = 3 - 6 \n" ); document.write( "-x = -3 \n" ); document.write( "Multiply both sides by -1 \n" ); document.write( "x = 3 \n" ); document.write( "Proof:- \n" ); document.write( "3(x + 2) – 4x = 3 \n" ); document.write( "3(3 + 2) - 4(3) = 3 \n" ); document.write( "3(5) - 12 = 3 \n" ); document.write( "15 - 12 = 3 \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " \n" ); document.write( " |
