Algebra.Com's Answer #319807 by ccs2011(207)![]() ![]() You can put this solution on YOUR website! Let R be Rizza's age, N be Norie's age \n" ); document.write( "R = 2N +1 \n" ); document.write( "(R-8) + (N-8) = R + 10 \n" ); document.write( "Lets solve for N in 2nd equation \n" ); document.write( "Subtract R on both sides, they cancel \n" ); document.write( "-8 +N -8 = 10 \n" ); document.write( "Combine like terms \n" ); document.write( "N -16 = 10 \n" ); document.write( "Add 16 on both sides \n" ); document.write( "N = 26\r \n" ); document.write( "\n" ); document.write( "Substitute into 1st equation to solve for R \n" ); document.write( "R = 2(26) + 1 \n" ); document.write( "R = 52 + 1 \n" ); document.write( "R = 53 \n" ); document.write( " |
