Solve the system by elimination method. x+y-6=0
x-y-8=0
when you eliminate y, what is the resulting equation?

The answer is x=7

and y=-1

On eliminating y the resulting equation is 2x=14

Step-by-step explanation:

Given x+y-6=0 [1]

and x-y-8=0 [2]

On eliminating y in eq [1]

y=6-x

Putting value of y in eq [2]

x-(6-x)-8=0

x-6+x-8=0

2x-14=0

2x=14

x=7

Putting x=7 in [1]

7+y-6=0

y+1=0

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
