Question

Which system of equations below has no solution?
y = 4x + 5 and y = 4x – 5
y = 4x + 5 and 2y = 8x + 10
y = 4x + 5 and y = One-fourthx + 5
y = 4x + 5 and y = 8x + 10

Answer 1

Answer:

Y=4x+5 and y=4x-5 has no solution

Because........

a1/a2=b1/b2 but not equal to c1/c2

Answer 2

$\longrightarrow \huge\underline \mathfrak{solution}$

1. This equation has no solution since it's c1/c2 ratio is not equal.
2. This equation has solution since all the ratios are equal.
3. This equation has an unique solution.
4. This equation has an unique solution.
