3/4 x 8,4 +2,8 x 1va1/2
1va1/2 la hon so nha
\(\frac{3}{4}\)x 8,4 + 2,8 x \(1\frac{1}{2}\)
= 0,75 x 8,4 + 2,8 x \(\frac{3}{2}\)
= 0,75 x 8,4 + 2,8 x 1,5
= 6,3 + 4,2
= 10,5

1va1/3 + 1va 1/5 x y- 4/5=2va4/5
= \(\frac{4}{3}\)+ \(\frac{6}{5}\)x y - \(\frac{4}{5}\)= \(\frac{14}{5}\)
= \(\frac{8}{15}\)+ \(\frac{6}{5}\)x y = \(\frac{14}{5}\)
\(\frac{6}{5}\)x y = \(\frac{14}{5}\)- \(\frac{8}{15}\)= \(\frac{6}{15}\)
y = \(\frac{6}{15}\): \(\frac{6}{5}\)
y = \(\frac{1}{3}\)
