✔ 最佳答案
4 = 44 + 4x
4x = - 40
x = - 10
(as you suggest)

Yes, it is the ONLY solution...

4 - 4x = 44
- 4x = 44 - 4
- 4x = 40
x = 40/(-4)
x = -10

Hope that helps xxx

Let me see:

4 - 4x = 44
4x = 4 - 44
4x = -40
x = -40/4
x = -10

You are correct.

Yes it is.

4 - 4x = 44

Substract 4 from both sides

-4x = 40

Divide both sides by -4

x = -10

4 - 4x = 44
- 4x = 44 - 4
- 4x = 40
x = 40/(-4)
x = -10

Yeah that's right
