Question 886676
Gabriela is 42 years old and Omar is 3 years old. 
How many years will it take until Gabriela is only 4 times as old as Omar?
-----------
Let the number of years be "x"::
Equation::
42+x = 4(3+x)
42+x = 12 + 4x
3x = 30
x = 10 
In 10 years Gabriela will be 52 and Omar will be 13
4*13 = 52
