170+540:х=260 100+х:40=115 уравнение

Question

170+540:х=260 100+х:40=115


уравнение

Answer 1

170+540:х=260
540:х=260-170
540:х=90
х=540:90
х=6

100+х:40=115
х:40=115-100
х:40=15
х=15*40
х=600

Answer 2

540/x=260-170
540/x=90
X=6

X/40=15
X=600

Comments

540 / x = 260 - 170

---

540 / x = 90

---

x = 540 / 90

---

x = 6

---

40 + x = 115 - 100

---

40 + x = 15

---

x = 40 - 15

---

x = 40 * 15

---

x = 600
