Question

Решите уравнение х+6.74=9 5.4-х=3,827 х-5,257=19,743

Answer 1

X+6.74=9
x=9-6.74
x=2.26

5.4-x=3.827
x=5.4-3.827
x=1.573

x-5.257=19.743
x=19.743+5.257
x=25

Comments

а можно еще одно решить?

---

да

---

(29,3-х)+54=19,743

---

x=54+29.3-19.743

---

(29,3 - x) + 54 = 19,743

---

x=63.557

спасибо большое

Answer 2

X + 6,74 = 9
x = 9 - 6,74
x = 2,26
__________
2,26 + 6,74 = 9
9 = 9

5,4 - x = 3,827
x = 5,4 - 3,827
x = 1,573
____________
5,4 - 1,573 = 3,827
3,827 = 3,827

x - 5,257 = 19,743
x = 19,743 + 5,257
x = 25
_______________
25 - 5,257 = 19,743
19,743 = 19,743
