Therefore,

Priya's way is correct to solve the equation.

Other person Strategyis Equation is

23+ x -23=4-23

Step-by-step explanation:

Given:

Jada and Priya are trying to solve the equation,

23+ x=4

For Jada way of calculation :

I think we should multiply each side by 32 because that is the reciprocal of 23.

Also Reciprocal of 23 is $\dfrac{1}{23}$

We have

$32\times (23+x)=32\times 4$ ...Which is INCORRECT

For Priya way of calculation :

I think we should add -23 to each side because that is the opposite of 23.

We have

23+ x +(-23)=4+(-23)

plus minus= minus , (+ - = - )

23 will get cancelled and she will get "x"

$23+ x -23=4-23\\\\x=-19$ ...Which is CORRECT

Hence Priya's way is correct to solve the equation.

The other Person strategy to solve will be:

I think we should subtract 23 to each side because that is the opposite of 23.

We have

$23+ x -23=4-23\\\\x=-19$ ...Which is also CORRECT.

Therefore,

Priya's way is correct to solve the equation.

Other person Strategyis Equation is

23+ x -23=4-23
