Question

Tìm x : (x - 7,6 + 12,75) - 9,3 = 16,72

Answer 1

\(x-7,6+12,15=16,72+9,3\)

\(x-7,6+12,15=26,02\)

\(x-7,6=26,02-12,15\)

\(x-7,6=13,87\)

\(x=13,87+7,6\)

\(x=21,47\)

Answer 2

(x-7,6+12,75)=16,72+9,3

(x-7,6+12,75)=26,02

x-7,6            =26,02-12,75

x-7,6            =13,27

x                  =13,27+7,6

x                  =20,87
