Question

здравствуйте,не могли бы решить эти уравнения?​

Answer 1

1)

$(x + \frac{12}{5} ) \times \frac{1}{8} = 2.3$

$\frac{5x + 12}{40} = 2.3$

$5x + 12 = 92$

$5x = 92 -12$

$5x = 80$

$x = 16$

2)

$8x = 5.6 + 3.2 = 8.8$

$x = 1.1$

3)

$11x + 1.8 = 9.5$

$11x = 9.5 - 1.8 = 7.7$

$x = 0.7$

4)

$12.5y = 1$

$y = 0.08$

5)

$13.6y = 1.8 + 3.64 = 5.44$

$y = 0.4$
