Answer 1

$5)x \times 9 = 810 \div 3 \\ x \times 9 = 270 \\ x = 270 \div 9 \\ x = 30 \\ x \div 8 = 280 \div 4 \\ x \div 8 = 70 \\ x = 70 \times 8 \\ x = 560 \\ 52 \div x = 193 - 180 \\ 52 \div x = 13 \\ x = 52 \div 13 \\ x = 4$

Answer 2

Х×9=810÷3

Х×9= 270

Х=270÷9

Х=30

30×9=810÷3

270=270

Х÷8=280÷4

Х÷8=70

Х=70×8

Х=560

560÷8=280÷4

70=70

52÷Х=193-180

52÷Х=13

Х=52÷13

Х=4

52÷4=193-180

13=13
