What are the steps for adding and subtracting mixed numbers with unlike denominators

Say we have 2/3 and 1/2.

Multiply 2/3 to make 4/6.

Multiply 1/2 to make 3/6.

Suddenly, you can do whatever you want with the problem because you are working with common denominators.

I hope that this helps.  If you get stuck on future problems, just find the thing that the two denominators have in common after multiplying them a few times.  An example would be 4 and 7.  The lowest number that they can multiply to that they have least in common is 28.

Well, there are different ways to do this if you are really familiar with fractions, but "officially" :P

1) convert mixed numbers to improper fractions.

rule:  a b/c = (ac+b)/c

2)  make all fractions have a common denominator...

a/b+c/d

(a/b)(d/d)+(c/d)(b/b)

(ad/bd)+(cb/bd)

3)

The simplify your final answer with greatest common denominator or convert back to mixed number if needed...

A solution for a pair of lines means that they are equal to each other. This occurs when they instersect. Since the lines have the same slope, but are not the same line, they are parallel, so they will never intersect. This means there are zero solutions.
Hope this helps!
