how to solve x-2y=8 and x=5-y using substitution method and showing work and please give me the correct answer

y = -1

Step-by-step explanation:

Set up

x-2y  = 8

Substitute 5-y for x

5 - y -2y = 8

Combine like terms

-3y + 5 = 8

Subtract 5 from both side

-3y = 3

Divide by -3

y = -1

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

multiply then divide
