Answer 2

$\huge {\boxed{\underline {\overline {\orange{answer}}}}}$

$x=\frac{1}{10}=0.1$

$\huge {\underline {\overbrace {\blue{solution}}}}$

22x+1-42x=-1

-20x+1=-1

-20x=-1-1

-20x=-2

$\huge \bold {\underbrace {\red{x=\frac{-2}{-20}}}}$

For better experience, Know proper Explanation:-

Given:- 22x+1 = 42x-1

Solution:- Subtract 42x from both sides.

22x+1-42x=-1

Combine 22x and -42x to get -20x.

-20x+1=-1

Subtract 1 from both sides.

-20x=-1-1

Subtract 1 from -1 to get -2.

-20x=-2

Divide both sides by -20.

$x=\frac{-2}{-20}$

Reduce the fraction

$\frac{-2}{-20}$

to lowest terms by extracting cancelling out -2.

$\huge \bold {\underbrace {\red{x=\frac{-2}{-20}}}}$
