Without the inclusion of an equality sign the expression given can not be considered to be an equation.
If they are inconsistent and you try to solve them you will get something like: 5=0, which of course isn't true so... you can't solve them
That depends on what type of equation it is because it could be quadratic, simultaneous, linear, straight line or even differential
You'd need another equation to sub in
solve it
If you solve such an equation for "y", you get an equation in the slope-intercept form.
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
you don't answer an equation, you solve an equation

you can only solve for one in an equation so it can equal something
