Algebra.Com's Answer #81234 by BrittanyM(80)![]() ![]() ![]() You can put this solution on YOUR website! Our first step is to get a common denomonator so we can cancel it out and word with whole numbers.\r \n" ); document.write( "\n" ); document.write( "Multiply (x-4)/2 by 10 in order for the denomonator to equal 20. \n" ); document.write( "Multiply 1/5 by 4 in order to get 20.\r \n" ); document.write( "\n" ); document.write( "Now, we may cancel out the denomonators on both sides of the equation. \n" ); document.write( "That leaves us with 10(x-4)-4=(7x+1)\r \n" ); document.write( "\n" ); document.write( "Now, using the distributive proporty, we have \n" ); document.write( "10x-40-4=7x+1 \n" ); document.write( "3x=45 \n" ); document.write( "x=15 \n" ); document.write( " |
