Let’s solve this maze step by step using substitution. We start at the “Start” box and follow the correct answer to the next box until we reach “Finish”.

Step 1: Start Box
Equations:
> x = -2y
> 4x + 3y = 10
Substitute x = -2y into the second equation:
4(-2y) + 3y = 10
→ -8y + 3y = 10
→ -5y = 10
→ y = -2
Now plug y = -2 into x = -2y:
x = -2(-2) = 4
✔ Solution:
(4, -2) → Go to the box labeled (4, -2)
---
Step 2: Box with (4, -2)
Equations:
> y = 4x + 15
> -5x - y = 3
Substitute y = 4x + 15 into the second equation:
-5x - (4x + 15) = 3
→ -5x - 4x - 15 = 3
→ -9x - 15 = 3
→ -9x = 18
→ x = -2
Now plug x = -2 into y = 4x + 15:
y = 4(-2) + 15 = -8 + 15 = 7
✔ Solution:
(-2, 7) → Go to the box labeled (-2, 7)
---
Step 3: Box with (-2, 7)
Equations:
> -2x + y = 12
> y = -5x - 9
Substitute y = -5x - 9 into the first equation:
-2x + (-5x - 9) = 12
→ -2x -5x -9 = 12
→ -7x -9 = 12
→ -7x = 21
→ x = -3
Now plug x = -3 into y = -5x - 9:
y = -5(-3) - 9 = 15 - 9 = 6
✔ Solution:
(-3, 6) → Go to the box labeled (-3, 6)
---
Step 4: Box with (-3, 6)
Equations:
> y = 3x - 10
> 3x + 4y = 5
Substitute y = 3x - 10 into the second equation:
3x + 4(3x - 10) = 5
→ 3x + 12x - 40 = 5
→ 15x - 40 = 5
→ 15x = 45
→ x = 3
Now plug x = 3 into y = 3x - 10:
y = 3(3) - 10 = 9 - 10 = -1
✔ Solution:
(3, -1) → Go to the box labeled (3, -1)
---
Step 5: Box with (3, -1)
Equations:
> x = 5y + 4
> 3x - 2y = -14
Substitute x = 5y + 4 into the second equation:
3(5y + 4) - 2y = -14
→ 15y + 12 - 2y = -14
→ 13y + 12 = -14
→ 13y = -26
→ y = -2
Now plug y = -2 into x = 5y + 4:
x = 5(-2) + 4 = -10 + 4 = -6
✔ Solution:
(-6, -2) → Go to the box labeled (-6, -2)
---
Step 6: Box with (-6, -2)
Equations:
> x = -y - 5
> x = 2y - 2
Set them equal since both equal x:
-y - 5 = 2y - 2
→ -5 + 2 = 2y + y
→ -3 = 3y
→ y = -1
Now plug y = -1 into x = -y - 5:
x = -(-1) - 5 = 1 - 5 = -4
✔ Solution:
(-4, -1) → Go to the box labeled (-4, -1)
---
That leads us to the
Finish box!

Final Answer:
The path is:
Start → (4, -2) → (-2, 7) → (-3, 6) → (3, -1) → (-6, -2) → (-4, -1) → Finish
