Đáp án:
\(\left[ \begin{array}{l}x=0,3\\x=-\frac{16}{75}\end{array} \right.\)
Giải thích các bước giải:
$(3,3 - 11x)(7x+\frac{2}{5} +2\frac{1-3x}{3})=0$
⇔$(3,3-11x)(7x+\frac{2}{5} +\frac{2}{3}-2x)=0$
⇔$(3,3-11x)(5x+\frac{16}{15})=0$
⇔\(\left[ \begin{array}{l}3,3-11x=0\\5x+\frac{16}{15}=0\end{array} \right.\)
⇔\(\left[ \begin{array}{l}x=0,3\\x=-\frac{16}{75}\end{array} \right.\)
