Question

(27+x):2+10=380+25*5

Answer 1

(27+x):2+10=380+25*5

​<=>(27+x):2+10=505

​<=>(27+x):2=505-10=495

​<=>27+x=595*2=990

​<=>x=990-27=963

Answer 2

(27+X):2+10=380+25x5

(27+X):2+10=505

(27+X):2=505-10

(27+X):2=495

27+X=495x2

27+X=990

X=990-27

X=963

Answer 3

\(\left(27+x\right):2+10=380+25.5\)

\(\Rightarrow\left(27+x\right):2+10=380+125=505\)

\(\Rightarrow\left(27+x\right):2=505-10=495\)

\(\Rightarrow27+x=495.2=990\)

\(\Rightarrow x=990-27=963\)

vậy x = 963
