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.
Answer: is 3x-12
12(6) =2
7b+12=5b
Subtraction property of equality
7b + 12 - 12 = 5b - 12
Simplifying
7b = 5b - 12
Subtraction property of equality
7b - 5b = 5b - 12 - 5b
Simplifying
2b = -12
Division property of equality
2b/2 = -12/2
Simplifying
b = -6
