Answer 1

a = 36

Explanation:

For the system to have no solution, the two lines must have the same slope and different y -intercept, that is, be parallel lines.

The slope of the first line is "-1/2" (negative one half) when we solve for y:

`y = -(1)/(2) x+(11)/(6)`

so we want the slope of the second line to be the same, and the y-intercept to be different:

`y=-(a)/(72) x+(61)/(36)`

We see that the y-intercepts are different, so all is needed now is to find the appropriate a that gives a slope = -1/2, and that a value is 36.
