Problems on Linear equation in one variable

Solve the following equations for x:

  1. CodeCogsEqn%20(6)

  2. CodeCogsEqn%20(7)

  3. CodeCogsEqn%20(8)

Ist) x= 42/25
2nd) x=5
3rd) x=15.6

For first question check the working below:

-4(-5x+3)-3(x-5)-2(x-3)=9
20x-12-3x+15-2x+6=9
15x=9+12-15-6
15x = 21-21
15x = 0
x = 0.

How did you get x = 42/25 ? Check all your workings in detail.
