Answer 1

Answer:

1) b=8

2) b=8

3) v=4

4) r=4

5) m=-1

6) n= 5

7) x=1

8) k= -6

9) n=-6

Step-by-step explanation:

1)3(-8-3b)=-96

-24-9b=-96

-9b= -96+24

-9b = -72

b= -72

-9

b= 8

2) 16-5b=4b-7b

16= 4b-7b+5b

16=-3b+5b

2b= 16

b= 16

2

b=8

3) -14+4v=-6+2v

4v-2v=-6+14

2v= 8

v= 4

4) 5r-3=4r+1

5r-4r=1+3

r = 4

5) 6m+8=1-m

6m+m=1-8

7m = -7

m= - 7

7

m=-1

6) 4+2n=-6+4n

4+6=4n-2n

10 = 2n

n= 5

7) -6(1-x)=2-2x

-6+6x= 2-2x

6x+2x=2+6

8x=8

x= 1

8) -7(3k+8)=28-7k

-21k -56=28-7k

-21k+7k=28+56

-14k= 84

k= 84

- 14

k= -6

9) -8(n+8)-n=14+4n

-8n-64-n=14+4n

-9n-64= 14+4n

-9n-4n=14+64

-13n= 78

n= 78

- 13

n= -6
