Solving Equations of the First Degree with One Unknown

Equations with one unknown.

A first degree equation with one unknowns can be expressed as

a1 x + c1 = a2 x + c2                                  (1)

The equation can be transformed to

x = (a1 - a2) / (c2 - c1)                 (1b)

Example - Solving a First Degree Equation with One Unknown

22 x - 10 = 12 x + 20 

22 x - 12 x = 20 - (-10)

(22 - 12) x = 30

x = 30 / 10

x = 3
