Answer:
-9 and 2
Step-by-step explanation:
-9 x 2
The answer is A because you have to use the process of substitution
Answer: r= -1000
Step-by-step explanation:
Solve for r by simplifying both sides of the equation, then isolating the variable
People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)
5a + 2b = 660
-2a - 2a = -420
3a=240
a= 80
*3 people purchased good seats.
Now we can plug that number in
5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats
