# indeterminate equations

Indeterminate equations are simultaneous equations which, for some reason, have an infinite number of solutions. Examples are

*x* + *y* = 4

2*x* + 2*y* = 8

where the two equations are equivalent, and

*x* + *y* = *z*

½*x* + 6*y* + 3 = 8*z*

where there is insufficient data.
