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:
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
