Question

помогите пожалуйста задания 6. срочно.​

Answer 1

Ответ:

1)

$y - 165 = 620 + 173$

$y = 620 + 173 + 165$

$y = 958$

2)

$a \div 15 = 54 \div 18$

$18a = 810$

a = 45

3)

$800 - x = 870 - 610$

$x = 870 - 610 - 800$

x = - 540

4)

$y - 420 = 600 - 56$

$y = 600 - 56 + 420$

y = 964

5)

$55 \times x = 820 - 710$

$55x = 820 - 710$

$55x = 110$

x = 2

6)

$300 - x = 42 \times 2$

$300 - x = 84$

$- x = 84 - 300$

$- x = - 216$

x = 216
