Algebra.Com's Answer #71890 by elima(1433) ![]() You can put this solution on YOUR website! 2(4 - 2r) = -2(r + 5) \n" ); document.write( "First distribute 2 on both sides; \n" ); document.write( "8-4r=-2r-10 \n" ); document.write( "Now subtract 8 and add 2r to each side; \n" ); document.write( "8-4r-8+2r=-2r-10-8+2r \n" ); document.write( "that cancels out the 8 on the right side and 2r on the left, now we have r on one side; \n" ); document.write( "-4r+2r=-10-8 \n" ); document.write( "-2r=-18 \n" ); document.write( "divide -2 on both sides; \n" ); document.write( " \n" ); document.write( "r=9 \n" ); document.write( ":) \n" ); document.write( " |
