Answer:
Solution : -x + 24 = -3 x -20
= -x + 24 = 60 ( - ) x ( - ) = ( + )
= -x = 60 - 24 ( When a number from one side
move to another side the
negative and positive signs changes. )
= -x = 36
( If -x = 36 then x = -36 due to
additive inverse. )
= x = -36
Verification : 36 + 24 = -3 x -20
60 = 60
Hence, verified.
