Question

решите, уравнение:

15 (3-x) -5(x +11)=1-19x

Comments

(45-x)-(5x+11)=1-19x

---

45х-х-5х-11=1-19х

---

45х-х-5х-11-1+19х=0

---

45х-х-5х+19х-11-1=0

---

58х-12=0

Answer 1

45-15x-5x-55=1-19x
-10-20x=1-19x
-20x+19x=1+10
-x=11
x=-11

Answer 2

15 (3-x) -5(x +11)=1-19x
45-15х - 5х - 55= 1-19x
45-55-1=15х+5х-19х
-11=х
х=-11
