Answer:
<em>Alex sold 330 white chocolate bars</em>
Step-by-step explanation:
let the milk chocolate candy be x and the white chocolate candy be y. then
then 2x+3y=990----1)
x+y=330-----2)
from eq 2) ⇒ x=330-y---------3)
Putting eq 3 in eq 1
2(330-y) +3y=990
660-2y+3y=990
y=990-660=330-----------4)
Putting eq4 in eq1
2x+3(330)=990
2x+990=990
2x=990-990
2x=0
x=0---------------------------5)

Answer:
x=16/3=5.33.
Step-by-step explanation:
Isolate x on one side of the equation.
2+x3=18
2+x*3=18
2+x*3-2=18-2 (First, subtract 2 from both sides.)
18-2 (Solve.)
18-2=16
x*3=16
x*3/3=16/3 (Then, divide by 3 from both sides.)
16/3=5.33
x=16/3=5.33
In conclusion, the final answer is x=16/3=5.33.
