: ALGEBRA PREP

LESSON 3 : SOLVING LINEAR EQUATIONS

### Solving Equations Involving Addition, Subtraction or
Division

**Principle of Equivalent Equations:**

The same operation may be performed on both sides of an
equation and produce an equivalent equation.
Hence :

**The same amount may be added or subtracted from each side
of a given equation.**

**Both sides of an equation may be multiplied or divided by
the same amount.**
