Answer:
(2,-1) ; (-1, 4) ; ( 5 , -6)
Step-by-step explanation:
-5x - 3y = -7
Put x = 2 , -5*2 - 3y = -7
-10 -3y = -7
-3y = -7 + 10
-3y = 3
y = 3/-3
y = -1
(2,-1)
Put x = -1 ; -5 *-1 -3y = -7
5 - 3y = -7
-3y = -7 - 5
-3y = -12
y = -12/-3
y = 4
(-1, 4)
Put x = 5, -5*5 -3y = -7
-25 - 3y = -7
-3y = -7 + 25
-3y = 18
y = 18/-3
y = -6
( 5 , -6)
substitute in the equation:
Answer:
168 unlimited-ride passes.
Step-by-step explanation:
50x+20y=10680
x+y=282
Multiply.
20(x+y=282)
20x+20y=5640
Subtract.
50x-20x+20y-20y=10680-5640.
30x=5040
x=168
Hope this helps plz hit the crown :D
75,000 x .04 = 7,000 (agency fee)
