I don't know how to type equations out, like squared, etc. So bare with me. You should be able to see what i am getting at.
1) x - 2y = 11
x + 2y = -13 Answer x=-1, y=-6
2) x(squared) + 6 - 40 = 0
answer x=-10 and 4
I am just asking what they are called. Thanks.

Question 1 (Simultaneous Equations)
2x = - 2
x = - 1
- 1 + 2y = - 13
2y = -12
y = - 6
Question 2 (Quadratic Equation)
Assuming question is:-
x² + 6x - 40
(x - 10) (x + 4) = 0
x = 10 , x = - 4

The first type of equations are called 2-system simultaneous linear equations. There will only one set of solution for x and y.
The second type of equations are quadratic equations because the maximum power of x is 2.

the first one is a double linear equation
the second is a quadratic

Those are equations. In one case you have two equations with two variables, in the other one just one equation with one variable.
