Answer 2

Heya dear user !!!

Here is your answer,

================================

Three times a number added to 12 gives -6 .

Solution :-

Let the number be x

=> 12+ 3x = -6

=> 3x = -6-12

=> 3x = -18

=> x = -18/3

=> x = -6

================================

Verification

L.H.S = 12+3x

= 12+(3×-6)

= 12+ (-18)

= 12 - 18

= -6 = R.H.S (hence, verified)
