Câu hỏi: Cho \(\overrightarrow a  = \left( {2;1} \right),\overrightarrow b  = \left( {3;4} \right),\overrightarrow c  = \left( { - 7;2} \right).\) Tìm vectơ \(\overrightarrow p \) sao cho : \(4\overrightarrow p  - 2\overrightarrow a  = \overrightarrow b  - 3\overrightarrow c \)

A \(\overrightarrow p  = \left( { - 7;0} \right)\)

B \(\overrightarrow p  = \left( {7;0} \right)\)

C \(\overrightarrow p  = \left( {5;0} \right)\)

D \(\overrightarrow p  = \left( { - 5;0} \right)\)
