Algebra.Com's Answer #71679 by edjones(8007)![]() ![]() You can put this solution on YOUR website! -4/3(2x+1)=-x-2 \n" ); document.write( "multiply -3 times each side: 4(2x+1)=3x+6 \n" ); document.write( "8x+4=3x+6 \n" ); document.write( "subtract 3x and 4 from each side: 5x=2 \n" ); document.write( "divide 5 into each side: x=2/5 \n" ); document.write( "When you converted the fraction on the left side you should only multiply 3 times -4/3 and NOT times (2x+1). this gives you -4(2x+1)=-3x-6. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Ed \n" ); document.write( " |
