Question

Решите пожалуйста !!!
Очень срочно!!!

Answer 1

А1.

$1)7x = 35 \\ x = 5 \\ 2) - \frac{3}{8} = 1 \\ x = \frac{8}{3} \\ 3) - x = - 0.03 \\ x = 0.03 \\ 4) - 12x = \frac{3}{5} \\ x = \frac{1}{20} = 0.05$

А2.

$2y - 5 = - 3 \\ 2y = - 3 + 5 \\ 2y = 2 \\ y = 1$

А3.

$1)8x - 5 = x - 40 \\ 8x - x = - 0 + 5 \\ 7x = - 35 \\ x = - 5 \\ 2)7x + 22 = x - 14 \\ 7x - x = - 14 - 22 \\ 6x = - 36 \\ x = - 6 \\ 3)19 - 6x = 0 \\ 6x = 0 - 19 \\ 6x = - 19 \\ x = \frac{19}{6}$

А4.

$5(8x - 1) - 7(4x + 1) + 8(7 - 4x) = 9 \\ 40x - 5 - 28x - 7 + 56 - 32x = 9 \\ 40x - 28x - 32x = 9 + 5 + 7 - 56 \\ - 20x = - 35 \\ x = - 35 \div ( - 20) \\ x = \frac{7}{4} = 1.75$

Всегда пожалуйста)))
