Three numbers are in the ratio 2:4:7. If the first number is multiplied by 4, the result is 9 less than the sum of the other two. find all three numbers.
\n" ); document.write( ":
\n" ); document.write( "WE can call it 2x; 4x; 7x without changing the ratio
\n" ); document.write( "1st number = 2x
\n" ); document.write( "2nd number = 4x
\n" ); document.write( "3rd number = 7x
\n" ); document.write( ":
\n" ); document.write( "Write an equation for:
\n" ); document.write( "\"If the first number is multiplied by 4, the result is 9 less than the sum of the other two.\"
\n" ); document.write( "4(2x) = 4x + 7x - 9
\n" ); document.write( "8x = 11x - 9
\n" ); document.write( "8x - 11x = -9
\n" ); document.write( "-3x = -9
\n" ); document.write( "x = + 3
\n" ); document.write( ":
