You can put this solution on YOUR website!
The ratio of Zoya’s age to Nelya’s age is 1:4.
\n" ); document.write( "let x = the multiplier
\n" ); document.write( "then
\n" ); document.write( "x = Z's age
\n" ); document.write( "and
\n" ); document.write( "4x = N's age
\n" ); document.write( ":
\n" ); document.write( " Twenty years from now, Nelya will be twice as old as Zoya will be then.
\n" ); document.write( "4x + 20 = 2(x+20)
\n" ); document.write( "4x + 20 = 2x + 40
\n" ); document.write( "4x - 2x = 40 - 20
\n" ); document.write( "2x = 20
\n" ); document.write( "x = 20/2
\n" ); document.write( " x= 10 is the multiplier, there
\n" ); document.write( "Z is 10 and N is 40
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement
\n" ); document.write( "\"Twenty years from now, Nelya will be twice as old as Zoya will be then.\"
\n" ); document.write( "40 + 20 = 2(10 + 20)
\n" ); document.write( "60 = 2(30) \r
\n" ); document.write( "
\n" ); document.write( "
