Đáp án:
435-(x+16)=425
x+16=435-425
x+16=10
x =10-16
x =-6
(1,7× x+$\frac{3}{4}$)×$\frac{7}{4}$= 5-$\frac{7}{6}$
(1,7× x+$\frac{3}{4}$)×$\frac{7}{4}$=$\frac{23}{6}$
(1,7× x+$\frac{3}{4}$) =$\frac{23}{6}$÷$\frac{7}{4}$
(1,7× x+$\frac{3}{4}$) =$\frac{46}{21}$
1,7× x =$\frac{46}{21}$ -$\frac{3}{4}$
1,7× x =$\frac{121}{84}$
x=$\frac{121}{84}$ :1,7
x =$\frac{605}{714}$
