Question

решите уравнение
(60-10х):4+12=22

Answer 1

$frac{60 - 10x}{4} + 12 = 22 \ frac{60 - 10x}{4} times 4 + 12 times 4 = 22 times 4 \ 60 - 10x + 48 = 88 \ 108 - 10x = 88 \ 108 - 88 = 10x \ 20 = 10x \ x = 2 \ frac{60 - 10 times 2}{4} + 12 = 22 \ frac{60 - 20}{4} + 12 = 22 \ frac{40}{4} + 12 = 22 \ 10 + 12 = 22 \ 22 = 22$

Answer 2

(60 - 10х) ÷ 4 + 12 = 22
30 - 5х + 24 = 22
54 - 5х = 44
- 5х = 44 - 54
- 5x = - 10
x = 2
Ответ: х = 2.
