Question

hi help i need your questions step by step answer ok ​

Answer 1

Step-by-step explanation:

1) 2(x+ 4) = 12

2x + 8 = 12

2x = 12-8

2x= 4

x= 4/2

x= 2

2) 3(n-5) = 21

3n -15 = 21

3n = 21 +15

3n = 36

n =36/3

n = 12

3) 3(n-5) = -21

3n - 15 = -21

3n = -21 + 15

3n = -6

n = -2

4) -4(2+x ) = 8

-8 -x = 8

-x = 8+ 8

- x = 16

x = -16

5) 4(2-x) = 8

8 - x = 8

-x = 8 -8

- x = 0

x=0

6) 4= 5(p-2)

4 = 5p -10

14 = 5p

p= 14/5

7) -4 = 5(p-2)

-4 = 5p -10

-6 = 5p

p = -6/5

8) 16= 4+3(t+2)

16= 4+ 3t+ 6

16= 10 + 3t

16-10 = 3t

6 = 3t

t= 2

9) 4+5(p-1) = 34

4 + 5p -5 = 34

-1 + 5p = 34

5p = 34 +1

5p = 35

p = 7

10) 0= 16 +4 (m-6)

16+ 4m -24 = 0

-8 +4 m = 0

4m = 8

m = 2

pls mark me as brainliest answer

it took half an hour

hope it helps

have a good day
