Question

как решить уравнение -4,92-(0,08y+5.12)=-0.88-y

Answer 1

-4,92-(0,08y+5.12)=-0.88-y 
-4.92 - 0.08y - 5.12 +y + 0.88 = 0
-10.04 + 0.88 + 0.92 y = 0 
9.16 + 0.92y = 0
 0.92y =-9.16 
$\ y=- frac{916}{92} =- 9 frac{88}{92} =-9 frac{11}{23}$
Ответ: у=$-9 frac{11}{23}$

Answer 2

-4.92-0.08y-5.12=-0.88y
-0.08y-10.04-(-0.88)y=0
0.8y-10.04=0
0.8y=10.04
y=10.04/0.8
y=12.55

Answer 3

-0.08y-10.04+y=0.88 0.92y-19.04=0.88 0.92y=9.16 y=9.16/0.92=9.957
