Answer:
106 - 8h = 34
Whenever a math question says "when <em>h </em>= 9," they mean you substitute this number where <em>h </em>is in the equation.
106 - 8(9) = 34
106 - 72 = 34
34 = 34
This means the fact that h = 9 <u>is a solution for h.</u>

Answer:
Step-by-step explanation:
point p is on line r
line r passes through point P
line r contains point P
So if there is 7 people and shakes the hand of everyone once it would be 6 shakes for one person to shake all the 7 people.6 because himself is counted as one.
So if we multiply 6x7 we would have our answer which in this case is 42
42 handshakes in total from everybody.

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...
