Question

x*4+1/2*x=55,35

Answer 1

nếu X*4+1:2*X=55,35

thì X=12,3

Answer 2

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

Answer 3

Lời giải

\(x\cdot4+\frac{1}{2}\cdot x=55,35\)

\(x\cdot\left(4+\frac{1}{2}\right)=55,35\)

\(x\cdot\frac{9}{2}=55,35\)

      \(x=55,35:\frac{9}{2}\)

      \(x=12,3\)
