That equation cannot be solved since there are 2 unknown in the equation (x and y) but only 1 equation. The number of unknowns must be equal to the number of equations (for simultaneous equations)

Simultaneous equation is nothing: it cannot exist.A system of simultaneous equations is a set of 2 or more equations with a number of variables. A solution to the system is a set of values for the variables such that when the variables are replaced by these values, each one of the equations is true.The equations may be linear or of any mathematical form. There may by none, one or more - including infinitely many - solutions to a system of simultaneous equations.

This cannot be solved for numerical answers. There must be 2 equations if there are 2 variables.

This cannot be solved. If you have 2 unknowns (a,b) then you must have 2 equations.

Simultaneous equations are where you have multiple equations, often coupled with multiple variables. An example would be x+y=2, x-y=2. To solve for x and y, both equations would have to be used simultaneously.

This cannot be solved. It needs 2 equations to solve for 2 unknowns.

By substitution or elimination in simultaneous equations.

By solving the simultaneous equations the values of x and y should be equal to the given coordinate

They are straight line graphs that work out the solutions of 2 equations or simultaneous equations

A system of equations is a set of equations with more than one variable dealing with the same material. If there are 2 variables, then the system must have 2 equations before it can be solved. 3 variables need 3 equations, etc.

The points of intersection. The coordinates of such points will be the solutions to the simultaneous equations representing the curves.

The coefficients and constant in one of the equations are a multiple of the corresponding coefficients and constant in the other equation.
