Answer 1

$\huge\boxed{\fcolorbox{white}{pink}{Answer:}}$

1-4x=-11

-4x=-11-1

-4x=-12

x=$\frac{-12}{-4}$

x=3

Answer 2

Step-by-step explanation:

1 - 4x = -11

= -4x = -11 - 1  ( because after transposing , the value of the number becomes the opposite )

= -4x =- 12

= x = -12/ -4

= x = 3

Now lets check it ,

1 - 4x = -11

= 1 - 4(3) = -11

= 1 - 12  = -11

= -11 = -11

LHS = RHS

Hence , it is correct.
