Gabriella is X years old her sister Felisha is 6 years older than she is their mother is twice as old is Felicia their aunt Tany
Makovka662 [10]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~

Let me lay down the Given, and than I'll solve the question...

<em>Felisha</em> is 6 years older than <em>Gabriella</em><em> - (y)</em>

<em>Their Mother</em> is 2 times older than <em>Felisha</em>

<em>Their Aunt (Tanya - [x] )</em> is X years older than <em>Their Mother</em>

<em /><u><em>We are solving for how old is Tanya? ...</em></u>

**I stated Gabriella with a y instead of an X so that the equation does not look confusing, feel free to replace my y with "<em /><em>Gabriella(X)</em>", when writing/typing your answer...

**When I use the variable <em>Z</em>, this is how many years Tanya is older than the Mother...


To find how many years Tanya is older than the Mother: Z = 2 * (6 + y)

Now... the answer is: X = (2 * (6 + y)) + Z

I stated it this way, because we have to add Felisha's and Gabriella's age first, and than your multiply that age <em>Total</em> by 2 to get the Mother's age...

(8x4+64x3+3x-28)÷(x-8)
mamaluj [8]

check the picture below.


recall that the division is done with the dividend and divisor sorted in descending order, notice the dividend has a jump from x³ to x, so the x² is missing, but is really there, but it has a coefficient of 0, as you see there in red, so we add any missing terms on either side.
