( a - 48 : 4 + 2 ) x 5 + 12 x 12 = 204

( a - 12 + 2 ) x 5 + 12 x 12 = 204

( a - 14 ) x 5 + 12 × 12 = 204

a - 14 x 5 + 12 x 12 = 204

a - 70 + 144 = 204

a - 214 = 204

a = 204 + 214

a = 218

(a-48:4+2)x5+12=204:12
(a-48:4+2)x5+12=17
(a-48:4+2)x5=17-12
(a-48:4+2)x5=5
(a-48:4+2)=5:5
(a-48:4+2)=1
(a-48:4)=2-1
a-48:4=1
a-12=1
a=12+1
a=13
