Answer:
y=10r
Step-by-step explanation:
Ok so if each member of the jazz band sold the same amount of tickets, r, then we can write a linear equation (no exponents or anything). let y be the total number of raffle tickets sold. If they all sold the same amount, then we can simply multiply the number of people by the tickets they individually sold.
First you had to add by seven from both sides of equation form.

Then simplify by equation.

Next, you multiply by two from both sides of equation form.

And finally, simplify by equation.





Final answer: 
Hope this helps!

5x-2x+6x+40-9+1-x+3x-8+15+7
First you would combine like terms:
5x - 2x + 6x - x + 3x = 11x and
40 - 9 + 1 - 8 + 15 + 7 = 46, so the simplified expression would be
11x + 46
Step-by-step explanation:
Let the number be x.
ATQ,
Malachy halves the number and gets an answer of 67.3.

This the equation for the given statement.
It can also be written as :

Hence, this is the required solution.
