Algebra.Com's Answer #321025 by gwendolyn(128)![]() ![]() You can put this solution on YOUR website! Let Rizza's age=R \n" ); document.write( "Let Norie's age=N \n" ); document.write( "Let Rizza's age 8 years ago=R-8 \n" ); document.write( "Let Norie's age 8 years ago=N-8 \n" ); document.write( "Let Rizza's age 10 years from now=N+10\r \n" ); document.write( "\n" ); document.write( "Two equations can be formed from the information in the question and the variables I have set.\r \n" ); document.write( "\n" ); document.write( "R=2N+1 \n" ); document.write( "(R-8)+(N-8)=R+10\r \n" ); document.write( "\n" ); document.write( "First, we cancel out the two 'R's in the second equation: \n" ); document.write( "-8+N-8=10 \n" ); document.write( "Then we should add 16 to both sides. \n" ); document.write( "N=26 \n" ); document.write( "Next, we should plug in our value of N. \n" ); document.write( "R=2N+1 \n" ); document.write( "R=54+1 \n" ); document.write( "R=55 \n" ); document.write( "So, Rizza is 55 and Norie is 26. \n" ); document.write( " |
