What is an easy way to solve an equation with two variables?

Answer 1

You can't solve an equation that has two variables. If you need to find unique

values for the variables, then you need as many separate, independent equations

as there are variables. If one equation has 'x' and 'y' in it, it has an infinite number

of solutions. If you have another equation with 'x' and 'y' in it, you work the two of

them together, you get one single solution, and you know what numbers 'x' and 'y'

must be to make both equations true.

When you say "an easy way", it means you're looking for a process that works by

itself when you turn the crank, without any need to understand what's going on.

There is no such process to give you.

There is a way that you can make the solution of equations easy for yourself.

Here are the steps:

-- Go to every math class. No ditching.

-- Stay awake in every class. Follow what's going on, with no phoning, texting,

gaming, or doodling.

-- Do the homework, on time, before the next class after it's assigned.

-- Math is peculiar: If there's something you can't understand, you can't save it up,

because you're going to need it for the next thing. If there's something you can't do,

then get together with the teacher, or a friend or an adult who knows that stuff,

and go over it with them until you get it.

If you follow this process, then solving equations will be easy and you'll ace all of

the tests. But you'll also discover that none of that will matter! Something even better

will come along ... you'll actually LEARN stuff, and you'll know how to use it to make

your life easier and better later on.
