Definition of simultaneous:
Happening, existing, or done at the same time.
Systems of equations are solved simultaneously. You find a common solution (if one exists).

i think the question should be what are simultaneous equations.
these equations are solved simultaneously and the solution set should satisfy both/all equations.
if we have an equation x+y=4,depending on the value we ascribe to any one variable there will be corresponding values for the other variable satisfying the equation.thus come of the ordered pairs can be (0,4);(1,3);(2,2);(3,1) and so on
if we take another equation x-y=4 some of the ordered pairs can be ((1,-3);(2,-2);(3,-1);(0,-4) and so on
but only one ordered pair namely (4,0) will satisfy both the equations simultaneously or in other words to get a solution set which satisfies both the equations we have to solve both simultaneously and not in isolation.
hope i have explained it and this is the answer you were looking for

You need at least two for them to be simultaneous.

It's when you have two (or more) variables, and two (or more) equations--since with only one equation you can only ever solve for one variable.

Ex: 3x + 2y = 9
x+ y = 13

then using the two, you can get x = 13-y
3(13-y) + 2y = 9
39 - 3y + 2y = 9
39 - y = 9
y=30

And then substituting back
x + 30 = 13
x = -17

Simultaneous equations is two or more equations in which the values of the unknown quantities entering them are the same at the same time in both or in all.
