$(54 \div 6) + (2 \times 4) = 9 + 8 = 17.$

-------------------------------------------------------------------

$(12 + 4) - (16 \div 4) = 16 - 4 = 12.$

-------------------------------------------------------------------

$63 \div 7 + (45 - 8) = 9 + 37 = 46.$

-------------------------------------------------------------------

$x - 4 = 36$

$x = 36 + 4$

$x = 40$

Ответ : 40 .
