Darko is 5 years old and Zana is 8 years old. How old was Zana when she was twice as old as Darko? plz step by step

6 years old

Step-by-step explanation:

8-5=3

Which means their age difference is 3.

3×2=6

16

Step-by-step explanation:

Whenever it says twice, it means to multiply by 2. So you take Zara's age, it being 8, and multiply it by 2 like it says to.

Here's an equation to help explain how I got this answer better.

2 * 8 = 16

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
