Answer 2

Step-by-step explanation:

The Question Can Be One Of These Two Forms Match This Question With Your Book.

a) 3(x+7)42 a) 3(x+7) = 42

=> 3×42(x+7) => 3x+21 = 42

=> 126(x+7) => 3x = 42-21

=> 126x + 882 . Ans => 3x = 21

b) 4(x-2)12 => x = 21/3

=> 4×12(x-2) => x = 7 . Ans

=> 48(x-2) b) 4(x-2) = 12

=> 48x - 96 . Ans => 4x-8 = 12

c) p-1=3 => 4x = 12+8

=> p = 3+1 => 4x = 20

=> p = 4 . Ans => x = 20/4

=> x = 5 . Ans
