Question

12 x X + 12 x 125% x X =27,27

Answer 1

=>  X(12+12.125%) =27,27

      X.27=27,27

      X=27,27/27

      X=1,01

     Vậy X=1,01

 

Answer 2

12x X x(1+125%)=27,27

12x X x(1+5/4)=27,27

12x X x 9/4=27,27

12xX=27,27 :9/4

12xX=12,12

X=12,12:12

X=1,01

Answer 3

12 . x + 12 . 125% . x =27,27

12 . (x +125% . x) = 27,27

x + \(\frac{5}{4}\).x =27,27 :12 =\(\frac{909}{400}\)

x. (1 + 5/4) = 909 /400

x. 9/4 =909/400

x = \(\frac{101}{100}\)=1,01
