помогите пожалуйста прошу!!!​

Answer 1

$1)\\(x - 5) *(x + \frac{3}{23} ) = 0\\\\x - 5 = 0\\x + \frac{3}{23} = 0\\\\x = 5\\x = - \frac{3}{23} \\\\OTBET : x_{1} = -\frac{3}{23} , x_{2} = 5\\\\2)\\5x + 10 = 5x\\\\10 = 0\\OTBET : HEBEPEH\\\\3)\\1,1y - 0,9y + 4 = 4 + 0,2y\\\\1,1y - 0,9y = 0,2y\\\\0,2y = 0,2y\\\\4)\\x * (x + 3\frac{8}{15} ) * (x - 10,2) = 0\\\\x * (x + \frac{53}{15}) * (x - \frac{51}{5} ) = 0\\\\x = 0\\x + \frac{53}{15} = 0\\x - \frac{51}{5} = 0\\\\x = 0\\x = - \frac{53}{15} \\x = \frac{51}{5}$

Ответ : $x_{1} = - \frac{53}{15} , x_{2} = 0 , x_{3} = \frac{51}{5}$
