7 x; L. J0 V: ~0 p" Q) I　　Example:
2 n6 ^& W, ]8 \) _　　To solve ax+b=c use the following steps:
+ H4 |) A/ _4 ^" i　　1.ax+b=c, subtract b from both sides
; R6 c3 E) r3 h! m! z1 R　　2.ax=c-b, divide both sides by a
  r/ T: |: m4 Q- C0 ?4 A- f　　3.x=(c-b)/a
　　Remember:
　　All linear equations of one variable can be written as ax+b=c and the solution is x=(c-b)/a.
