SOLVING MORE COMPLICATED LINEAR EQUATIONS
WITH INTEGER COEFFICIENTS

An example is given below. For a complete discussion, read the text.

EXAMPLE:
Solve:   3 - 2x = 5x + 1
Solution:
Write a nice clean list of equivalent equations:
3 - 2x = 5x + 1 (original equation)
3 = 7x + 1 (add  2x  to both sides)
2 = 7x (subtract  1  from both sides)
2/7 = x (divide both sides by  7 )
x = 2/7 (write in the most conventional way)
Answer:   x = 2/7
