Answer:
1
Step-by-step explanation:
Answer:
F is 0
Step-by-step explanation:
If you divide X on both sides to get X on one side, it will end with F = -2 + 2, which is 0
Similarities
Adding or subtracting a number from both sides.
Multiplying or dividing both sides by a positive number.
Applying an increasing function to both sides.
Simplifying one or both sides.
Differences
Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.
When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.
Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.

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...
