Parallel lines never meet and so parallel equations do not have any simultaneous solution.

Tell me the equations first.
Equations are never parallel, but their graphs may be. -- Write both equations in "standard" form [ y = mx + b ] -- The graphs of the two equations are parallel if 'm' is the same number in both of them.
There are people who use this web site that can and will solve equations.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
The answer depends on the nature of the equations.
If the slope of the equations are the same then they are parallel If the slope of the equations are minus reciprocal then they are perpendicular If the slope of the equations are different then they are neither
Yes, they are. If you solve 2x + 7y = 6 for y, you get y = (-2x + 6) / 7. If you solve 7y + 2x + 6 = 0 for y, you get y = (-2x - 6) / 7. As you can see, both equations have the same slope. Therefore they are parallel. You can punch those equations into a graphing calculator and visually verify that they are indeed parallel.
You solve equations with fractions the same way you solve other equations. You perform various arithmetic operations on both sides of the equals sign until you get the result you want.
You need as many equations as you have variables.
One can solve equations of motion by graph by taking readings of the point of interception.
Its harder to solve the equations with grande numbers
