Now how can I be 10 years old and 4 years before birth at once :(

Those are two parallel lines, they never cross.

THERE IS NO SOLUTION !!!!
You can tell the lines are parallel if you solve each equation for y. The number in front of the x is the slope as in y =mx+b

6y =3x + 10 divide by 6 to get m=1/2

second equation 6y = 3x -4 m = 1/2

or you could graph both equations and see that they are parallel.
