Question

Solve the following equations:
(a) 2(x + 4) = 12 (b) 3in-5) = 21
(d) -4(2 + x) = 8 (e) 4(2-x) = 8
(c) 3(1-5) = -21
please fast​

Answer 1

a.2(x+4)=12⇒x+4=

2(x+4)=12⇒x+4= 2

2(x+4)=12⇒x+4= 212

2(x+4)=12⇒x+4= 212

2(x+4)=12⇒x+4= 212 ⇒x+4=6

2(x+4)=12⇒x+4= 212 ⇒x+4=6⇒x=6−4⇒x=2

b.3(n−5)=21⇒n−5= 3

3(n−5)=21⇒n−5= 321

3(n−5)=21⇒n−5= 321

3(n−5)=21⇒n−5= 321 ⇒n−5=7

3(n−5)=21⇒n−5= 321 ⇒n−5=7⇒n=7+5⇒n=12

Answer 2

Answer:

x+4=6
