Tìm \(\large x\), biết: \(\large (432 \times 134 – 432 \times 38 – 432

Tìm \(\large x\), biết:

\(\large (432 \times 134 – 432 \times 38 – 432 \times 45 – 432 \times 51 + 1) \times x + 6 \times x = 1092\)

• A.

  \(\large x\) = 145

• B.

  \(\large x\) = 156

• C.

  \(\large x\) = 167

• D.

  \(\large x\) = 178

\(\large (432 \times 134 – 432 \times 38 – 432 \times 45 – 432 \times 51 + 1) \times x + 6 \times x = 1092\)
\(\large (432 \times (134 – 38 – 45 – 51) + 1) \times x + 6 \times x = 1092\)
\(\large (432 x 0 + 1) \times x + 6 \times x = 1092\)
\(\large x + 6 \times x = 1092\)
\(\large x \times 7 = 1092\)
\(\large x = 1092 : 7\)
\(\large x = 156\)
