Question

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

1. Jada says, "I think we should multiply each side by  because that is the reciprocal of ."
2. Priya says, "I think we should add  to each side because that is the opposite of ."

Which person's strategy should they use?

Answer 1

Priya's strategy solves the equation. x=4-2/3 = 3 1/3 or 10/3 or x = 3.333...

Jada's strategy only makes the equation more complicated and no closer to a solution

Jada's strategy would work if the equation had been (2/3)x = 4, with x=(3/2)4 = 6
