a) ( x + 268 ) x 137 = 48498
( x + 268 ) = 48498
x + 268 = 354
x = 354 - 268
x = 86

Sửa đề: \(\left(46\times369+46\right)-\left(268\times45+268\right)\)
\(=46\times\left(369+1\right)-268\times\left(45+1\right)\)

[ y + 268 ] x 268 = 4849

bài này có dư nha
(x + 268)× 137 =49498
x+268=49498:137
x+268=\(\frac{49498}{137}\)
