Solving Equations of the First Degree with One Unknown
Equations with one unknown.
A first degree equation with one unknowns can be expressed as
a_{1} x + c_{1} = a_{2} x + c_{2} (1)
The equation can be transformed to
x = (a_{1}  a_{2}) / (c_{2}  c_{1}) (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
