Answer:
45 tickets for the matinee were sold
Step-by-step explanation:
let m represent the number of matinee tickets sold and
let e represent the number of evening tickets sold.
Create a system of equations and solve for m
m + e = 130 → (1) ( total ticket sales )
6m + 10e = 1120 → (2) ( income from tickets sold )
multiplying (1) by - 10 and adding the result to (2) will eliminate e
- 10m - 10e = - 1300 → (3)
add (2) and (3) term by term to eliminate e
(6m - 10m) + (10e - 10e) = 1120 - 1300
- 4m + 0 = - 180
- 4m = - 180 ( divide both sides by - 4 )
m = 45
the number of matinee tickets sold was 45
a. 0
b. 1
c. 9 + 6i
d. -9 + 6i
An equation is formed of two equal expressions. In the given equation (9–6i)×m = 9–6i, the value of m is 1.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
In the given equation (9–6i)×m = 9–6i, the value of m can be found as,
(9–6i)×m = 9–6i
Divide both the sides of the equation by (9–6i),
m = 1
Hence, In the given equation (9–6i)×m = 9–6i, the value of m is 1.

two negatives make a postive as they cancel each other out
5 - - 3 = 5 + 3 = 8
the only way the answer could be - 2 is if the original question said 5 + - 3 = - 2
