1.50x + 450 = 3x
450 = 3x - 1.50x
450 = 1.50x
450/1.50 = x
300 = x
300 copies must be sold to break even

Step-by-step explanation:
Answer:
Solution tends to infinity
Step-by-step explanation:
Given the expression
(3x-2)/(x+3)-1=(3x-3)/(x+1)-2
This can also be expressed as;
(3x-2)/x+2 = 3x-3/x-1
3x-2/x+2 = 3(x-1)/x-1
3x-2/x+2 = 3
Cross multiply
3x-2 = 3(x+2)
3x-2 =3x+6
Collect like terms
3x-3x =6+3
0x = 9
x = 9/0
x = infinity
Hence the expression had no solution. It tends to infinity
