Question

Solve the equation. (a) -4(2+x) =8. (b) -5(p-2) =10​

Answer 1

Step-by-step explanation:

a. -4(2+x) =8

-8-4x=8

-4x=8+8

-4x=16

x=-4

b.-5(p-2) =10

-5p+10=10

-5p=10+10

-5p=20

p=-4

Answer 2

Answer:

a) x = -4.

b) x = 0.

Step-by-step explanation:

Given :-

a) -4(2+x) =8

-8 -4x= 8.

-4x = 8+8

-4x = 16

-x = 16/4

x= -4

b) -5(p-2) = 10

-5p +10= 10

-5p = 10-10

-5p = 0

-p= 0/5

p= 0

Verify, putting the value

a) -4(2-4)= 8

-8 +16= 8

8 = 8

Hence RHS = LHS

b) -5(0-2) = 10

0+ 10 = 10

10 = 10

Hence RHS = LHS
