a system of equations
They are called simultaneous equations.
equal equations.
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
Graph both equations on the same graph. Where they intersect is the solution to the system of equations
Equivalent Equations
There is no special name. Two totally unrelated equations could have the same solution(s).
