They can be used to find two unknown values with two equations.
A simultaneous equation
No because it's not a simultaneous equation but some kind of algebraic expression
Simultaneous suggests at least two equations.
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
Simultaneous equations have the same solutions.
simultaneous equations have identical solutions
Simultaneous equation
p q and p q cannot be a useful part of a system of simultaneous equations since they are the same!
Yes, for solving simultaneous equations.
They look like a cross
That depends on what type of equation it is because it could be quadratic, simultaneous, linear, straight line or even differential
Without any equality signs the given terms can't be considered to be simultaneous equations.
