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:

15x = 21-21
15x = 0
x = 0.

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


Correct! Good work again @Saanvi.S

sir i could do only first two questions third i could not understand

I could only do the first two problems sir.
