How are equations with one varible compared to equations with two variable. how are they alike and diffrent?

Answer 1

very different methods of solving besides u get a polynomial by multiplying 2 or more linear =ns.

Answer 2

One difference is that you need as many equations as you have variable to solve a system of equations. So an equation with one variable can be solved, but an equation with two variables must have another equation using at least one of those variables, to be solved.

Answer 3

Equations in one variable are called linear equations they have one unknown and thus one value is to be found.
Equations in two variables are called simultaneous equations have two unknown values and thus two values are to be calculated
