You should probably combine like terms. For example, look below for an explanation: 2x - 3 = 4x + 5 + 3 + 3 ----------------- 2x = 4x + 8 -4x -4x ----------------- -2x = 8 ---- --- -2 -2 ------------------ x = -4

Algebraic equations with two variables will need two equations to be able to solve it. Then, you can solve it with either substitution, adding/subtracting them together, or graphing! Those are the basic steps... For example: An instance of substitution: 2x + 1 = y + 2 x + y = 3 You could isolate y in the second equation to equal y = 3-x. Then in the first equation, substitute y with what it equals to 2x + 1 = 3-x+2 Then you can solve for x!
You have Boolean operators (such as AND & OR) on variables, rather than mathematical operations (+ - etc). The variables can only have one of two states (values) though (True/False, on/off, 1/0).
It is not possible to solve one linear equation in two variables for either of the variables.
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
Product means the answers when two variables are multiplied together. Such as, 4X3 the product would be 12.
