Here the given expression is
We need to find the value of y when x =3 . So we substitute the value of x in the given expression.
So when x=3, y=0.4 and that's the required answer.

Please mark me brainlest.✌✌
30b + 100u = 900
5b + 25u = 200....multiply by -6
------------------
30b + 100u = 900
-30b - 150u = - 1200 (result of multiplying by -6)
------------------add
-50u = - 300
u = 6 <== upgrated phones sold
30b + 100u = 900
30b + 100(6) = 900
30b + 600 = 900
30b = 900 - 600
30b = 300
b = 10 <== basic phones sold
