ANSWER
1a)
The given system of equation is:

and

We make x the subject in equation (2) to get;

We put equation (3) into equation (1) to get;

We expand the bracket to get,


This implies that,

This statement is false.
Hence the system has no solution.
1b)
Let us write the two systems in the slope-intercept form;
For the first equation, we have

Thus implies that,


For the second equation, we have:


We can see that, the two equations are parallel since they have the same slope.
Also the two equations will never meet since they have different y-intercepts.
Hence the system has no solution.
