數學唔識呀...help←"送(30分)

1)ax-b+c=0
ax=b-c
x=(b-c)/a

2)d-e=fx-cx
d-e=x(f-c)
x=(d-e)/(f-c)

3)v=u+at
at=v-u
a=(v-u)/t

4)ax+c=dx-b
c+b=dx-ax
c+b=x(d-a)
x=(c+b)/(d-a)

1 ax-b+c=0
ax=b-c because move to the another side + change to-
x=(b-c)/a becases move to the otherside x change to /
2 d-e=fx-cx
d-e=x(f-c) because x(f-c)=fx-cx
(d-e)/(f-c)=x
x=(d-e)/(f-c)
3 v=u+at
v-u=at because +u move to the other side will be -u
(v-u)/t=a because when axt move the t to another side it will change to /t
a=(v-u)/t
4 ax+c=dx-b
ax-dx=-b-c
x(a-d)=-b-c
x=(-b-c)/(a-d)
5 because there are two unknow and you have no question so i can anser you
6 because there are two unknow and you have no question so i can anser you

1)ax-b+c=0
ax=b-c
x=(b-c)/a

2)d-e=fx-cx
d-e=x(f-c)
x=(d-e)/(f-c)

3)v=u+at
at=v-u
a=(v-u)/t

4)ax+c=dx-b
c+b=dx-ax
c+b=x(d-a)
x=(c+b)/(d-a)

5)如果p=100和v=5(??)
6)如果R=100、K=60和 l =20(??)

1.ax-b+c=0
ax-b =-c
ax=-c+b
x=(-c+b)
—
a
2.d-e=fx-cx
d-e=x(f-c)
x= (d-e)
—
(f-c)
3.v=u+at
v-u=at
a= v-u
—
t
4.ax+c=dx-b
ax-dx=-b-c
x(a-d)=-b-c
x=-(b-c)
—
-(d-a)
x=(b-c)
—
(d-a)
Q5、6不知你問咩？

1.ax=b-c
x=(b-c)/a
2.d-e=x(f-c)
x=(d-e)/(f-c)
3.at=v-u
a=(v-u)/t
4.dx-ax=b+c
x(d-a)=b+c
x=(b+c)/(d-a)
5同6你好似打少左d野...你check下我再答...

1.ax-b+c=0
ax=b-c
x=(b-c)/a
2.d-e=fx-cx
d-e=x(f-c)
x=(d-e)/(f-c)
3.v=u+at
v-u=at
a=(v-u)/t
4.ax+c=dx-b
dx-ax=b-c
x(d-a)=b-c
x=(b-c)/(d-a)
5同6無式，計唔到

1.)ax-b+c=0
ax=b-c
x=(b-c)/a

2.)d-e=fx-cx
d-e=x(f-c)
x=(d-e)/(f-c)

3.)v=u+at
v-u=at
a=(v-u)/t

4.)ax+c=dx-b
ax-dx=-b-c
x(a-d)=-b-c
x=(-b-c)/(a-d) [or x= (b+c)/d-a)]

唔知你5~6題既問題
所以做唔到...
