Let r = R's age now
\n" ); document.write( "Let n = N's age now
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement;
\n" ); document.write( ":
\n" ); document.write( "\"rizza's age is one year more than twice norries's age.\"
\n" ); document.write( "r = 2n + 1
\n" ); document.write( ":
\n" ); document.write( "\" eight years ago, the sum of their ages was equal to rizza's age ten years from now.\"
\n" ); document.write( "(r-8)+(n-8) = r + 10
\n" ); document.write( ":
\n" ); document.write( "r + n - 16 = r + 10
\n" ); document.write( ":
\n" ); document.write( "r - r + n = 10 + 16
\n" ); document.write( ":
\n" ); document.write( "n = 26 yrs is N's age now
\n" ); document.write( "\":
\n" ); document.write( "we know r = 2n + 1
\n" ); document.write( "r = 2(26) + 1
\n" ); document.write( "r = 53 yrs is R's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See how those solution work in the statement
\n" ); document.write( "\"eight years ago, the sum of their ages was equal to rizza's age ten years from now.\"
\n" ); document.write( "(53-8) + (26-8) = 53 + 10
\n" ); document.write( "45 + 18 = 63; confirms our solutions\r
\n" ); document.write( "
