Jada and Priya are trying to solve the equation 23+x=4.

Jada says, “I think we should multiply each side by 32 because that is the reciprocal of 23.”
Priya says, “I think we should add -23 to each side because that is the opposite of 23.”
Which person’s strategy should they use? Why?
Write an equation that can be solved using the other person’s strategy.

Priyas

Step-by-step explanation:

First you want to isolate the variable. To do that you would add -23 to 23 making it 0. You'd do the same to the other side making it -19. So x= -19

Check

23+-19=4

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
