help with math homework?

Question

hi im a freshman in high school who needs help with this math. can someone help me answer these questions?

Solve each formula in terms of the given variable
1. 3n-t= s;t

2. b+3/e=f/2;e

3. w=2xyz; y

4. k=3mh+3;h

5. ab=6+cd; a

6. 2a+4b=d;b

7. 4xy+3=5z; y

8. -2(3a-b)=c;b

Answer 1

It just means get it in terms of the letter they have specified.
1)t=3n-s
2)eb+3=ef/2
eb-ef/2=-3
e(b-f/2)=-3
e=-3/(b-f/2)
3)y=w/2xz
4)h=k-3/3m
5)a=(6+cd)/b
6)b=(d-2a)/4
7)y=(5z-3)/4x
8)b=c/2 +3a

Answer 2

1. 3n-t= s;t
t = 3n-s
2. b+3/e=f/2;e
3/e = f/2 -b = (f-2b)/2
e = 6/(f-2b)
3. w=2xyz; y
y= w/(2xz)
4. k=3mh+3;h
k-3 = 3mh
h =(k-3)/(3m)
5. ab=6+cd; a
a = (6+cd)/b
6. 2a+4b=d;b
4b= d-2a
b + (d-2a)/4
7. 4xy+3=5z; y
4xy = 5z-3
y = (5z-3)/(4x)
8. -2(3a-b)=c;b
-6a +2b =c
2b= c+6a
b = (c+6a)/2

Answer 3

1.
3n-t=s
t=3n-s

2.
b+3/e=f/2
3/e=f/2-b
...srry got stuck

3.
w=2xyz
w/2xz=y

4.
k=3mh+3
k-3=3mh
k-3/3m=h

5.
ab=6+cd
a=6+cd/b

6.
2a+4b=d
d-2a=4b
d-2a/4=b

7.
4xy+3=5z
4xy=5z-3
y=5z-3/4x

8.
-2(3a-b) =c
(3a-b)=c/2
-b=c/2-3a
b=-c/2+3a
