\(25\%.y+50\%.y-\frac{3}{4}.y+4.y=10\)
\(y.\left(\frac{1}{4}+\frac{1}{2}-\frac{3}{4}+4\right)=10\)
\(y.4=10\)
\(y=\frac{5}{2}\)
\(x.\frac{1}{4}-\frac{3}{4}=6:\frac{3}{4}\)
\(x.\frac{1}{4}-\frac{3}{4}=6.\frac{4}{3}\)
\(x.\frac{1}{4}=8+\frac{3}{4}\)

\(x=\frac{35}{4}:\frac{1}{4}\)
\(x=35\)
25% x y + 50% x y - 3/4 x y + 4 x y = 10
1/4 x y + 1/2 x y - 3/4 x y + 4 x y = 10
y x ( 1/4 + 1/2 - 3/4 + 4 ) = 10
y x 4 = 10
y = 10 : 4
y = 2.5
25%.y + 50%.y - \(\frac{3}{4}\).y + 4.y = 10
\(\frac{1}{4}\).y + \(\frac{1}{2}\).y - \(\frac{3}{4}\).y + 4.y = 10
y = 10 - 4 + \(\frac{3}{4}\) - \(\frac{1}{2}\)- \(\frac{1}{4}\)
y = 6
x. \(\frac{1}{4}\)- \(\frac{3}{4}\)= 6:\(\frac{3}{4}\)
x. \(\frac{1}{4}\)- \(\frac{3}{4}\)= 8
x. \(\frac{1}{4}\) = 8 + \(\frac{3}{4}\)
x. \(\frac{1}{4}\) = \(\frac{35}{4}\)
x = \(\frac{35}{4}\): \(\frac{1}{4}\)
x = 35
