\(\Leftrightarrow x\cdot\dfrac{9}{2}=55.35\)
hay x=12,3

x*4 + 1/2 * x = 55,35
x * ( 4 + 1/2 ) = 55,35
x * 4,5 = 55,35
x = 55,35 : 4,5
x = 12,3
Vậy x = 12,3

\(x\times4+\frac{1}{2}\times x=55,35\)
\(x\times\left(4+\frac{1}{2}\right)=55,35\)
\(x\times4,5=55,35\)
\(x=55,35:4,5\)
\(x=12,3\)
x x 4 + 1/2 x x = 55,35
x x (4 + 1/2) = 55,35
x x 4,5 = 55,35
x = 55,35 : 4,5
x = 12,3
Chúc bạn học tốt.

Y×4+1/2×y=55,35
Y×4+0,5×y=55,35
Y×(4+0,5)=55,35
Y×4,5=55,35
Y=55,35:4
Y=12,3
Vậy y=12,3

\(4x+\frac{1}{2}x=55,35.\)
\(\Leftrightarrow\left(4+\frac{1}{2}\right)x=55,35.\)
\(\Leftrightarrow4,5x=55,35\)
\(\Leftrightarrow x=12,3\)

\(x\cdot4+\frac{1}{2}\cdot x=55,35\)
\(=x\left(4+\frac{1}{2}\right)=55,35\)
\(=x\cdot4,5=55,35\)
\(\Rightarrow x=55,35:4,5\)
\(\Rightarrow x=12,3\)
\(x.4+\frac{1}{2}.x=55,35\)
\(\Leftrightarrow x.\left(4+\frac{1}{2}\right)=55,35\)
\(\Leftrightarrow x.\frac{9}{2}=55,35\)
\(\Leftrightarrow x=55,35:\frac{9}{2}\)
\(\Leftrightarrow x=\frac{123}{10}=12,3\)
(Tíck cho mìk vs nha!)

\(x\cdot4+\frac{1}{2}\cdot x=55,35\)
\(x\cdot\left(4+\frac{1}{2}\right)=55,35\)
\(x\cdot\frac{9}{2}=55,35\)
\(x=12,3\)
Ta có : x*4+x*1/2=55,35
x(4+1/2) = 55,35
x* 9/2 = 55,35
x = 12,3
