公式主項:
全部主項變換為x
x+a=b
c+x=d
x－a=b
c－x=d
ax+b=c
ax－b=c
a+bx=c
a－bx=c
(a+b)x=c
x(a－b)=c
a(x+b)=c
a(x－b)=c
要考試..........你地可以講解下!!!

✔ 最佳答案
1) x=b-a2) x=d-c
3) x=b+a
4) c-x=d
c=d+x
x=c-d
5)ax+b=c
ax=c-b
x=c-b/a
6)ax-b=c
ax=c+b
x=c+b/a
7)a+bx=c
bx=c+a
x=c+a/b
8)a-bx=c
a=c+bx
a-c=bx
x=a-c/b
9) x=c/a+b
10) x=c/a-b
11) a(x+b)=c
x+b=c/a
x=c/a-b
12) a(x-b)=c
x-b=c/a
x=c/a+b
