How do you solve algebra with two variables?

Answer 1

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!
