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:
Andrew is driving at a faster speed and they both started at the same place.
Answer:
No Solution
Step-by-step explanation:
12x + 3 = 72x + 5
subtract 12x from both sides
end up with
3 = 72x - 12x + 5
subtract 12x to 72x
3 = 60x + 5
-5 from both sides
-8 = 60x
since x is a bigger number the answer would be NO SOLUTION
12x + 3 = 72x + 5
I do not understand lins logic
x + 6 = 7x + 10
subtract 6 from both sides
x = 7x + 4
move 7x to the other side
7x = 4
divide 7
x = 0.5
Also wrong because I get how lin got that answer
My way
12x + 3 = 72x + 5
-12 x from both sides
3 = 60x + 5
+5 to other side
8 = 60x
if the x was on the other side it would make sense
but it is not so the Answer is NO SOLUTION
Hope this Helped :)
