Question

12 x X = 123 x 123 + 409

Answer 1

12 x X = 123 x 123 + 409

12 x X = 15129 + 409

12 x X = 15538

X = 15538 : 12

X = \(\dfrac{7769}{6}\)

Answer 2

\(12.X=123.123+409\)

\(12.X=15129+409\)

\(12.X=15538\)

\(X=15538:12\)

\(X=\dfrac{7769}{6}\)

Vậy \(X=\dfrac{7769}{6}\)

Ghi chú 12 . X = 12 x X
