Answer:
#adult tickets sold = 346
#student tickets sold = 812
Step-by-step explanation:
let 'x' = # adult tickets sold
let 'y' = # students tickets sold
System of Equations:
x + y = 1158
5x + y = 2542
I used the elimination method and multiplied the first equation by -1
-x - y = -1158
+<u> 5x + y = 2542</u>
4x = 1384
x = 346
346 + y = 1158
y = 812
Y2-Y1
Over X2-X1 and then there is your slode
1. (7 − 3i) • (2 − i)
It is simplified as follows:
14 - 7i -6i - 3
11 - 13i
2. <span>(−5 + 3i) • (1 − 2i)
</span><span>It is simplified as follows:
</span><span>-5 + 10i + 3i + 6
1 + 13i
3. (1 + 3i) + (2 − 5i)

3 - 2i
4. (6 + 2i) − (8 − 3i)
