Question

2. Solve the following equations:
(a) 2(x + 4) = 12 (b) 3(n-5) = 21
(d) - 4(2 + x) = 8 (e) 4(2 - x) = 8​

Answer 1

a)x+4 =12/4

x+4=3

x=3-4

x=-1

b)n-5=21/3

n-5=7

n=7+5

n=12

d)2+x=8/-4

2+x=-2

x=-2-2

x=4

e)2-x =8/4

2-x=2

2-2=x

0=x

I hope it is helpful for you

Answer 2

Answer:

your answers are

Step-by-step explanation:

a) 2x+8=12

=2x=12-8

=x=4/2

=x=2

b) 3n-15=21

3n=21+15

n=36/3

n=12

c) 3n-15= -21

=3n= -21+15

=n= -6/3

=n= -2

-8-4x=8

-4x=8+8

4x= -16

x= -16/4

x= -4

e) 8-4x=8

-4x=8-8

-4x=0

4x=0

x=0/4

x=0.

hope so it will help you
