Tìm x

x.73+x.27=500

4x+7x=15

Answer 1

x.73 + x.27 = 500

x.100 = 500

x = 5

Vậy...

4x + 7x = 15

11x = 15

x = 15/11

Vậy...

Answer 2

\(x\left(73+27\right)=500\)

\(100x=500\)

x=5

b, x(4+7)=15

11x=15

x=\(\frac{15}{11}\)

Answer 3

\(x.73+x.27=500\)

\(\Rightarrow x.\left(73+27\right)=500\)

\(\Rightarrow x.100=500\)

\(\Rightarrow x=500:100\)

\(\Rightarrow x=5\)

Answer 4

x . 73 + x . 27 = 500

x . ( 73 + 27 ) = 500

x . 100 = 500

x = 500 : 100

x = 5

4x + 7x = 15

=> 11x = 15

x = 15 : 11

x = 15/11

Answer 5

\(4x+7x=15\)

\(\Rightarrow11x=15\)

\(\Rightarrow x=\frac{15}{11}\)

Answer 6

\(x\cdot73+x\cdot27=500\)

\(\Rightarrow x\cdot(73+27)=500\)

\(\Rightarrow x\cdot100=500\)

=> x = 500 : 100 = 5

\(4x+7x=15\)

\(\Rightarrow(4+7)x=15\)

\(\Rightarrow11x=15\)

=> x = 15 : 11 = \(\frac{15}{11}\)

Answer 7

x.73+x.27=500

(73+27).x=500

100x=500

x=500/100

x=5

4x+7x=15 

(4+7)x=15

14x=15

x=15/14

#Shyn#

Answer 8

15/11=))

Answer 9

a) x . 73 + x . 27 = 500

x . ( 73 + 27 ) = 500

x . 100 = 500

x = 500 : 100

x = 5

Vậy: ...

b) 4x + 7x = 15

x . ( 4 + 7 ) = 15

11x = 15

x = 15 : 11

x = \(\frac{15}{11}\)

Vậy: ...
