30 points ​

Answer 1

See,

in the first step, 4 is multiplied by 2x-1

-2 is multiplied by x-5

5 is multiplied by x+1

due to brackets

in 2nd step, nothing is done, only -2x and 4 are rearranged.

in 3rd step, we add all values

5x has been transpositioned to lhs(left hand side)

-4 and 10 are transpositioned to rhs (right hand side)

bcoz they are transpositioned their signs change

In 4th step, we solve the values

8x-2x-5x

we get x

and

5+3+4-10

we get 2

signs are changed because values are transpositioned.

hope you got to understand this question.

thanks.

please mark as brainliesttttt...
