Question

Решите уравнение 3 – 5(х + 1) = 6 – 4х

Ответ____

Answer 1

3 - 5( x + 1 ) = 6 - 4x 
3 - 5x - 5 = 6 - 4x 
- 2 - 5x = 6 - 4x 
x = - 8

Comments

3-5х-5-6+4х=0

---

-х-8=0 -х=-8 х=8

---

3 - 5 - 6 = - 8 ; - 5x + 4x = - x ; - 8 - x = 0 ; x = - 8

Answer 2

3-5*(x+1)=6-4x
3-5x-5=6-4x
-5x-2=6-4x
-5x+4x=6+2
-x=8
x=-8
