Question

x  *  1/2 -  5  =  5

Answer 1

Ta có:

x  *  1/2 -  5  =  5

x * 1/2 = 10

x=10:1/2

x=20

Answer 2

x*\(\frac{1}{2}\)- 5 =5

=>\(\frac{1}{2}x=10\)

=> \(x=20\)

Answer 3

\(x.\frac{1}{2}-5=5\)

\(\Rightarrow x.\frac{1}{2}=5+5\)

\(\Rightarrow x.\frac{1}{2}=10\)

\(\Rightarrow x=10:\frac{1}{2}\)

\(\Rightarrow x=20\)

Answer 4

Ta có: \(x.\frac{1}{2}-5=5\)

\(\Rightarrow x.\frac{1}{2}=5+5\)

\(\Rightarrow x.\frac{1}{2}=10\)

\(\Rightarrow x=10:\frac{1}{2}\)

\(\Rightarrow x=10.2\)

\(\Rightarrow x=20\)

Vậy x=20

Answer 5

X x 1/2 - 5 = 5

=> X x 1/2 = 10

X = 10 : 1/2

X = 20
