Step-by-step explanation:
problem 1.
1. 6y = 30
2. y = 5
3. 3x + 2(5) = 16
4. 3x+10=16
5. 3x=6
6. x=2
solution: (2,5)
problem 2.
1. x=7
2. 4(2)-2y=18
3. 28-2y=18
4. -2y= -10
5. y=5
solution (7,5)
problem 3
10x=10
x=1
7(1) +y =-2
y=-9
(1,9)

Answer:
She is 17 miles from the airport.
Step-by-step explanation:
Formula
Taxi base + Taxi per mile cost(miles) = Uber base + Uber per mile cost(miles)
2.60 + 2.70m = 1.75 + 2.75m
subtract 2.70m from both sides of equation
2.60 = 1.75 + .05m
subtract 1.75 from both sides of equation
0.85 = .05m
divide .05 to both sides of equation
m = 17 miles
