In the following question, a is a real number. question: what choice of a would yield a system of linear equations with no solutions?
9x-14y=-3
2x-ay=-6

The value of a should be 3.11.

Step-by-step explanation:

Since we have given that

We need to find the value of a so that it would yield a system of linear equations with NO solutions.

As we know the condition of no solutions, it means the lines should be parallel.

i.e.

Consider the first two terms:

So, the value of a should be 3.11.
