The teacher will be very surprised to see your correct solution 😉

You have entered [src]

13*x - 6*x + 14*x = 420

$$14 x + \left(- 6 x + 13 x\right) = 420$$

Simplify

Detail solution

Given the linear equation:

13*x-6*x+14*x = 420

Looking for similar summands in the left part:

21*x = 420

Divide both parts of the equation by 21

x = 420 / (21)

We get the answer: x = 20
