Answer:
1 solution It is (-14, -12.5).
Step-by-step explanation:
3x−4y=8
4y−4x=6
Adding the 2 equations eliminates the 4y:
3x - 4x = 14
x = -14
So
-42 - 4y = 8
4y = -50
y = -12.5,
Answer:
one solution
Step-by-step explanation:
3x - 4y = 8 a₁ = 3 and b₁ = -4
-4x + 4y = 6 a₂ = -4 and b₂ = 4
Set of equations has on solution if
