Q2. solution for equation
![5(x+1)-3(3x-1)=15(x-2)](https://tex.z-dn.net/?f=5%28x%2B1%29-3%283x-1%29%3D15%28x-2%29)
![5x+5-9x+3 = 15x-30](https://tex.z-dn.net/?f=5x%2B5-9x%2B3%20%3D%2015x-30)
![-4x+8 = 15x-30](https://tex.z-dn.net/?f=-4x%2B8%20%3D%2015x-30)
![38 = 19x](https://tex.z-dn.net/?f=38%20%3D%2019x)
![$x=\frac{38}{19} = \boxed{2}$](https://tex.z-dn.net/?f=%24x%3D%5Cfrac%7B38%7D%7B19%7D%20%3D%20%5Cboxed%7B2%7D%24)
Q3. which is not equivalent to ![4(2x-1)=3(x+1)-2](https://tex.z-dn.net/?f=4%282x-1%29%3D3%28x%2B1%29-2)
Just try all the values.
None of them makes the equation equivalent.
![8x-4=3x+1-2](https://tex.z-dn.net/?f=8x-4%3D3x%2B1-2)
![5x=5](https://tex.z-dn.net/?f=5x%3D5)

Q4. if a<0 and b<0 which of the following is not positive
B. a+b
![a](https://tex.z-dn.net/?f=a%3C0%20%5Cimplies%20%5Ctext%7Ba%20is%20negative%7D)
![b](https://tex.z-dn.net/?f=b%3C0%20%5Cimplies%20%5Ctext%7Bb%20is%20negative%7D)

Answers and Step-by-step explanation:
Trade Discount = List prices x Trade discount rate,
For 40% Trade discount rate,
TRADE DISCOUNT =
7000 x 40% = $2,800
For 20% Trade discount rate,
Net amount = 7000 - 2800 = 4200
TRADE DISCOUNT =
4200 x 20% = $840
For 15% Trade discount rate,
Net amount = 4200 - 840 = 3360
TRADE DISCOUNT =
3360 x 15% = $504
Therefore, the Trade Discount amounts are: $2,800, $840 and $504 for 40/20/15 rates respectively.
