Solve using the addition prinsiple. Don't forget to check. - 2/3 + y = - 3/4

Answer 1

Hint: Add 2/3 to both sides

Answer 2

You mean - 2/3 + y = -3/4 + 2/3?

Answer 3

to check plug in the resulting value for y and see if it turns out true :)

Answer 4

If you add 2/3 to both sides you end up with

-2/3 + 2/3 + y = -3/4 + 2/3

Answer 5

-2/3 + 2/3 = 0 leaving you with

y = -3/4 + 2/3
