X - S<span>arah's age now 3x - </span><span>Ralph is 3 times as old as Sarah, now x+6 - </span>Sarah's age in 6 years 2(x+6)=2x+12 - R<span>alph will be only twice as old as Sarah will be in 6 years </span>Ralph's age in six year can be also written as 3x+6<span>
So </span>Ralph's age now is 3x. Ralph's age in six years is 2x+12 and 3x+6.
We can find age of Sara now, 2x+12=3x+6 3x-2x=12-6 x=6, Ralph's age now is 3x=3*6=18 Now Sara is 6 years old, Ralph is 18 years old.
