Question

a) (80.x-801) . 25=0

b) (x 1 -10). 64=64

 

Answer 1

a) (80.x-801) . 25=0

( 80.x - 801 ) = 0 : 25 

80.x - 801 = 0 

80.x = 0 + 801

80.x = 801 

x = 801 : 80

x = 10,0125

vậy x = ...

b) (x 1 -10). 64=64

(x.1 - 10) = 64 : 64

x.1 - 10 = 1

x.1 = 1 + 10

x.1 = 11

x = 11 : 1

x = 11

vậy x =...

Answer 2

a) 80.x - 801 = 0 : 25

80.x - 801 = 0

80.x =0 + 801

80.x = 801

x = 801 : 80

x =\(\dfrac{801}{80}\)

b) x1 - 10 = 64 : 64

x1 - 10 = 1

x1 = 10 + 1

x1 = 11

x = 11 : 1

x = 11

Answer 3

a) 80.x - 801 = 0 : 25

80.x - 801 = 0

80.x = 0 + 801

80.x = 801

x = 801 : 80

x =
