Answer:
x=10 and y=15
Step-by-step explanation:
1: Plug y into the equation
y=2x-5
5x-4(2x-5)=-10
2: Solve for x
-3x=-30
<em><u>x=10</u></em>
3: Plug x into the other equation
x=10
y=2(10)-5
4: Solve for y
<u><em>y=15</em></u>

Answer:
450 people paid the discounted fare and 750 people paid the regular fare.
Step-by-step explanation:
let r be regular fares paid and d be discounted fares paid
Total fares = 0.8r + 0.4d = 780
Since 1200 people paid the fares,
r + d = 1200 = Total people
Rearrange this formula:
r = 1200 - d
Substitute r into Total Fares formula
Total fares = 0.8r + 0.4d
780 = 0.8(1200-d) + 0.4d
780 = 960 - 0.8d + 0.4d
780 = 960 - 0.4d
0.4d = 180
d = 450
Sub d=450 into Total people formula
r + d = 1200 = Total people
r + 450 = 1200
r = 1200-450
r = 750
450 people paid the discounted fare and 750 people paid the regular fare.
