Algebra - Linear Equations
tutorial.math.lamar.edu › Classes › AlgJun 02, 2018 · To solve linear equations we will make heavy use of the following facts. If a = b a = b then a+c =b +c a + c = b + c for any c c. All this is saying is that we can add a number, c c, to both sides of the equation and not change the equation. If a = b a = b then a−c =b −c a − c = b − c for any c c.
