Question

X x 25 - x = 25 x 23 +25

Answer 1

\(x\times25-x=25\times23+25\)

\(x\times\left(25-1\right)=25\times\left(23+1\right)\)

\(x\times24=25\times24\)

\(x=\left(25\times24\right):24\)

\(x=25\)

Answer 2

X x (25 - 1) = 25 x (23 +1)

X x 24= 25 x 24

X x 25 = 24 : 24

X x 25 = 1

       X = 25 : 1

       X = 25

Answer 3

`x xx25-x=25xx23+25`

`x xx(25-1)=575+25`

`x xx 24=600`

`x=600:24`

`x=25`

Answer 4

\(x\times25-x=25\times23+25\)

\(\Rightarrow x\times25-x=600\)

\(\Rightarrow x\times25-x\times1=600\)

\(\Rightarrow x\times\left(25-1\right)=600\)

\(\Rightarrow x\times24=600\)

\(\Rightarrow x=600:24\)

\(\Rightarrow x=25\)

Vậy x = 25

Answer 5

x × 25 − x = 25 × 23 + 25

x × ( 25 − 1 ) = 25 × ( 23 + 1 )

x × 24 = 25 × 24

x = ( 25 × 24 ) : 24

x = 25
