Question

X x 12,25 - X + X x 2,75 = 1050

Answer 1

\(\Leftrightarrow Xx\left(12,25-1+2,75\right)=1050\)

\(\Leftrightarrow14xX=1050\)

\(\Leftrightarrow X=75\)

Answer 2

X x (12,25-1+2,75)=1050

X x 14 = 1050

X=1050/14

X=75

Answer 3

x . 12 ,25 - x + x . 2, 75 = 1050 

<=> x . ( 12,25 - 1 + 2,75 ) = 1050

<=> x . 14                           = 1050

<=> x                                     = 1050 : 14

<=> x                                    = 75

Vậy x = 75
