Question

Tìm X biết:   X :12 + X x 12 + X : 12 x 5 = 12300

Answer 1

x : 12 + x . 12 + x : 12 . 5 = 12300

x . 1/12 + x . 12 + x . 5/12 = 12300

x . 1/2 + x . 12 = 12300

x . 25/2 = 12300

x = 12300 : 25/2

x = 984

Vậy x = 984.

Answer 2

x=984

ủng hộ mk nha

Answer 3

X:12+Xx12+X:12x5=12300

X x \(\frac{1}{12}\)+ X x 12 + X x \(\frac{5}{12}\)= 12300

X x \(\frac{1}{2}\) + X x 12 = 12300

X x \(\frac{25}{2}\) = 12300

X = 12300 : \(\frac{25}{2}\)

X=984

  

Answer 4

x= 984 do ban a

Answer 5

X* 1/12+X*12+X*1/12*5=12300

X*25/2=12300

X=12300:25/2

X=984
