Answer:
1. One solution
2. Infinite solution
3. No solution
Step-by-step explanation:
1. y = -4x - 5.........eq 1
+ (y = -4x + 1)..........eq 2
---------------------
2y = -4
divide by 2
2y/2 = -4/2
y = -2
solve for x
put y in any equation
from equation 1
y = -4x - 5
-2 = -4x -5
combine the like terms
-2+5 = -4x
3 = -4x
divide by -4
3/-4 = -4x/-4
x = -0.75
One solution
2. -3x + y = 7
2x - 4y = -8
Infinite solution
3. 3x - y = 4
6x - 2y =8
No solution
