What operation must be done to both sides of the equation to solve for p- -3 7/9 = 5/6?
OLga [1]

Given equation:  p - -3 7/9 = 5/6

When you subtract a negative number you automatically change it to adding a positive number.

p - -3 7/9 = 5/6 → p + 3 7/9 = 5/6

To isolate p in this equation we need to subtract 3 7/9 to both sides.

p + 3 7/9 - 3 7/9 = 5/6 - 3 7/9

p = -161/18

_______
