(0,045:х+3,8×0,7)=37.1
0.045:х+2.66=37.1
0.045:х=37.1-2.66
0.045:х=34.44
х=34.44×0.045
х=1.5498

Извиняюсь, я не там скобку поставил: (0,045:x+3,8) × 0,7 = 37,1

---

0.0315:0.7х+2.66=37.1

---

0.0315:0.7х=37.1-2.66

---

0.0315:0.7х=34.44

---

0.7х=34.44×0.0315

---

0.7х=1.08486

---

х=1.08486:0.7

х=1.5498
