There are many jobs where one would have to use equations. Some of those jobs include those who work in computer programming, advertising, construction managers, financial managers, and architects.
It depends on the equations.
because you need maths in your life.. everyone does
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
A single equation is several unknowns will rarely have a unique solution. A system of n equations in n unknown variables may have a unique solution.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect

The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
The computer solves a very large system of partial differential equations.
Gaussian elimination is used to solve systems of linear equations.
Systems of equations don't equal numbers.

If they are quadratic equations then if their discriminant is less than zero then they have no solutions
Systems of equations can have just about any number of solutions: zero, one, two, etc., or even infinitely many solutions.
usually bank accountants ..... they use it to find out things like interest ans S.P , C.P etc..
