Question

34+76=306-s
55:х=60-5
44*4=5*х​

Answer 1

Пошаговое объяснение:

$34 + 76 = 306 - s \\ 110 = 306 - s \\ s = 306 - 110 \\ s = 196$

$55 \div x = 60 - 5 \\ 55 \div x = 55 \: \: \\ \frac{55}{x }= 55 \: \: | \times x\\55 = 55x \\ 55x = 55 \\ x = 1$

$44 \times 4 = 5x \\ 176 = 5x \\5 x = 176 \: \: | \div 5 \\ x = \frac{176}{5} = 35.2$
