Question

(324 : 6 + 345 : 5 ) × 2 + 1237 = 43 × A + 1354

Answer 1

(324 : 6 + 345 : 5 ) × 2 + 1237 = 43 × A + 1354
(162 + 69) x 2 + 1237 = 43 x A + 1354
231 x 2 + 1237 = 43 x A + 1355
462 + 1237 = 43 x A + 1355
1699 = 43 x A + 1355
43 x A = 1699-1355
43 x A = 344
A = 344:43
A = 8

Answer 2

(54 + 69)*2+1237=43*a+1354
123*2+1237=43*a+1354
246+1237-1354=43*a
1483-1354=43*a
129=43*a
a=129/43
a=3
