**Answer This Question**

Pls assist. Thx

p: 5u

e: u

after giving 16 e

r: 4(u-16) = 4u - 64

e: (u-16)

4u - 64 +184 = 5u

u = 120

at first, he has 120 erasers.

...

btw, this is not algebra.

anyway, do u see the green correction written :

4u +184 = pens ???

this means ur daughter has been taught the units and parts method.

pls check with her.

otherwise, u can google "units and parts method" and learn something new.
