Какой?

---

(x-25.92):7+11.205=306.7

---

(х-25.92):7=306,7-11,205=295,495; х-25,92=295,495÷7=42,21; х=42,21+25,92=68,13. х=68,13

---

4 *(2 x -3 ) + 12= 96

---

8х-12+12=96; 8х=96;96÷8=12;х=12

---

( x + 3.5) * 8 - 7.2 = 26.4

---

8х+24-7,2=26,4; 8х+24=33,6; 8х=9,6; х=1,2

спасибо огромное!!!
