Okay, so I know that as soon as someone tells me what method to use, I'm gonna instantly remember it, but right now, I can think of only 1 way to solve simultaneous equations, and that doesn't work so ...

Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that map math variables, instead of representing information using abstraction ...

In some simultaneous equations neither the two coefficients of \(x\) nor the coefficients of \(y\) match. You will need to find numbers to multiply each equation by so that one pair of coefficients ...
