(d) - 4(2 + x) = 8 (e) 4(2 - x) = 8
Solve the foll
(c) 3(n-5)=-21

Answer 1

Step-by-step explanation:

●▬▬▬▬๑۩Qᴜᴇsᴛɪᴏɴ۩๑▬▬▬▬▬●

Solve the following equations:

(a) 2(x + 4) = 12 (b) 3(n-5) = 21

(d) - 4(2 + x) = 8 (e) 4(2 - x) = 8

Solve the foll

(c) 3(n-5)=-21

●▬▬▬▬๑۩Aɴsᴡᴇʀ۩๑▬▬▬▬▬●

ᴀ) 2(x + 4) = 12

2x + 8 = 12

2x = 12-8

x = 4/2

x = 2

B) 3( ɴ - 5) = 21

3ɴ - 15 = 21

3ɴ = 21 + 15

ɴ = 36/3

ɴ = 12

ᴅ) -4(2+x) = 8

-8-4x = 8

-4x = -8-8

x= -16/-4

x = -4

ᴇ) 4(2-x) = 8

8 - 4x = 8

- 4x = 8-8

x = 1/4

Answer 2

(a) 2(x+4)=12

2x+8=12

2x=4

x=2

(b) 3(n-5)=21

3n-15=21

3n=36

n=12

(c) 3(n-5)=-21

3n-15=-21

3n=-6

n=-2

(d) -4(2+x)=8

-8-4x=8

-4x=16

x=-4

(e) 4(2-x)=8

8-4x=8

-4x=0

x=0
