Algebra.Com's Answer #62287 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! 3x-5(3x-7)=2(x+9)+45 First, lets get rid of parens\r \n" ); document.write( "\n" ); document.write( "3x-15x+35=2x+18+45 Next, we will subtract 35 and also 2x from both sides. This will get the unknowns on one side of the equation and the numbers on the other\r \n" ); document.write( "\n" ); document.write( "3x-15x+35-35-2x=2x-2x+18+45-35 now we will collect like terms \r \n" ); document.write( "\n" ); document.write( "-14x=28 divide both sides by -14\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x=-2-------------------------------ans\r \n" ); document.write( "\n" ); document.write( "CK\r \n" ); document.write( "\n" ); document.write( "3(-2)-5{3(-2)-7}=2(-2+9)+45\r \n" ); document.write( "\n" ); document.write( "-6-5(-6-7)=2(7)+45\r \n" ); document.write( "\n" ); document.write( "-6-5(-13)=14+45 \n" ); document.write( "-6+65=14+45 \n" ); document.write( "59=59\r \n" ); document.write( "\n" ); document.write( "Hope this helps----ptaylor\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
