Answer:
Markia had 14 cookies.
Step-by-step explanation:
Let's represent the total amount of cookies as y.
We know that after she gave away 4 cookies and divided the remainder by 2, she had 5 cookies left.
This can represented as an equation.
= 5
To solve this equation we have to isolate the y.
= 5
Multiply both sides by 2 to isolate the y - 4: y - 4 = 10
Add 4 to both sides to isolate the y: y = 14
The total amount of cookies is 14.
