Question

Solve the following equation
(a) 2(x + 4) = 12
(d) - 4(2 + x) = 8.4
. Solve the following equati
(a) 4 = 5(p-2)​

Answer 1

Step-by-step explanation:

a) 2(x+4)=12

=>2x+8=12

=>2x=4

=>x=2

b) -4(2+x)=8.4

=> -8-4x=8.4

=> -4x= 16.4

=> x= -4.1

c) 4=5(p-2)

=>4=5p-10

=>5p=14

=>p =14/5

Answer 2

Answer:

(a) 2(x+4)=12

2x+8=12

2x=12-8

2x=4

x=4/2

x=2

(b) -4(2+x)=8.4

-8-4x=8.4

-4x=8.4+8

-4x=16.4

x=16.4/4

x=4.1

(c) 4=5(p-2)

5(p-2)=4

5p-10=4

5p=4+10

5p=40

p=40/5

p=8
