Answer:
<h2>
A. ¹²/₅</h2>
Step-by-step explanation:
There is no solution for system of equations:
if: 
so first, we we need to transform the equations to the form where the coefficients at y will be the same:

Now we have b₁=b₂ and c₁≠c₂ so the system has no solution if a₁=a₂
5k = 12
÷5 ÷5
k = ¹²/₅

Answer:
<em>x - y = 2</em>
Step-by-step explanation:
First of all, you would combine like terms, giving you 4x - 4y + 1 = 9.
Next, subtract the numbers, which gives you 4x - 4y = 8.
Finally, divide both sides by 4, which will come to the conclusion of x - y = 2, the simplest form of which this equation can be broken down to.
