The complex roots of an equation is any solution to that equation which cannot be expressed in terms of real numbers. For example, the equation 0 = x² + 5 does not have any solution in real numbers. But in complex numbers, it has solutions.

Strictly speaking the above equation is a tautological equation or an IDENTITY. An identity is true for all values of any variables that appear in it. Thus, the above "equation" is true for all value of x. - that is, it has infinitely many solutions.

It does not have any solutions! 14.8 is a number, not an equation, inequality or question and so has no solutions.

No. If an equation has many solutions, any one of them will satisfy it.

The solutions of the equation (if any) remain unchanged.

It needs to have an equality or equality signs to have solutions for it.Without any equality signs the given expression can't be considered to be an equation although it might be possible to simplify it.

A linear equation is that of a straight line. Any one of the infinitely many points on the line will be solutions. If the equation is in terms of the variables x and y, just pick any two values of x, solve for y and the results will be the coordinates of two solutions.

There is no equation (or inequality) in the question and so there cannot be any solutions.

There are 0, or no solutions to these equations. If you rearrange each equation to look like an equation of a line, you will have the two lines:y = x -1 and y = x + 1, which are two parallel lines. They do not intersect at any point, so there is no solution.

Add the two equations together. This will give you a single equation in one variable. Solve this - it should give you two solutions. Then replace the corresponding variable for each of the solutions in any of the original equations.
