![]()
has an infinite number of solutions.
(b) Withas in your answer to part (a), find a particular solution to this system.
Hello mr_motivatorIf, when you're solving simultaneous equations, there's an infinite number of solutions, then the equations are not independent. In the case of 2 equations in 2 unknowns, this simply means that one equation is a multiple of the other. So here,, and both sides of the second equation are clearly twice the first.
When, any value of
will do to find a corresponding value of
.
