Use substitution
x + x + 4 = 2
2x = -2, x = -1
Y = -1 + 4, y = 3
Solution: (-1, 3)

Step-by-step explanation:
To find the total distance, Divide distance already walked by percentage:
8 / 0.55 = 14.55 km
She already walked 8 so now subtract:
14.55 - 8 = 6.55 km left to walk
Answer:
When x = 0, then y = -2
When y = 0, then x = 4
Step-by-step explanation:
We are given with the following equation;
x - 2y = 4
Now, we have to find the respective values of x and y for each value of x = 0 and y = 0.
Firstly, putting the value of x = 0;
x - 2y = 4
0 - 2y = 4
-2y = 4
y = = -2
This means that when x = 0, then y = -2.
Similarly, putting the value of y = 0;
x - 2y = 4
x - 0 = 4
x = 4
This means that when y = 0, then x = 4.
