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

You have entered [src]

3*x - 5*x - 7*x = 23

$$- 7 x + \left(- 5 x + 3 x\right) = 23$$

Simplify

Detail solution

Given the linear equation:

3*x-5*x-7*x = 23

Looking for similar summands in the left part:

-9*x = 23

Divide both parts of the equation by -9

x = 23 / (-9)

We get the answer: x = -23/9
