So all you do is you divide 2 1/2 by .25 and you get 10 then you know one fourth or 25% of that package is 10 berries so the rest or 30% left over is 30 berries.
Y = 3. To find this, you would subtract 11 from both sides.
x = -12. To find this, you would subtract 8 from both sides.
Always remember that what you do to one side, you must do to the other.
Let's assume
Mark's present age is x
so, his age 2 years ago will be
Marks age, X is six times his age 2 years ago
so, we will get equation as
