Dave and Rita’s combined age is 46 years.
\n" ); document.write( "d + r = 46
\n" ); document.write( " If Dave’s age is 5 years less than twice Rita’s age.
\n" ); document.write( "d = 2r - 5
\n" ); document.write( "rearrange for elimination
\n" ); document.write( "d - 2r = -5
\n" ); document.write( ":
\n" ); document.write( "d + r = 46
\n" ); document.write( "d -2r = -5
\n" ); document.write( "---------------subtraction eliminates d, find r
\n" ); document.write( "0 + 3r = 51
\n" ); document.write( "r = 51/3
\n" ); document.write( "r = 17 yrs is Rita's age
\n" ); document.write( "then
\n" ); document.write( "d + 17 = 46
\n" ); document.write( "d = 46 - 17
\n" ); document.write( "d = 29 yrs is Dave's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement:
\n" ); document.write( "\"Dave’s age is 5 years less than twice Rita’s age.\"
\n" ); document.write( "29 = 2(17) - 5
\n" ); document.write( "29 = 34 - 5\r
