\(\left(x-10\right).5=20\)
\(x-10=4\Rightarrow x=4+10=14\)
( x - 10 ) x 5 = 20
x - 10 = 20 : 5
x - 10 = 4
x = 4 + 10
x = 14
(X - 10) X 5 = 20
X - 10 = 20 : 5
X - 10 = 4
X = 4 + 10
X = 14
BẠN CHO MÌNH NHÉ, PLEASEEEEEE
( x - 10 ) x 5 = 100 - 80
( x - 10 ) x 5 = 20
x - 10 = 20 : 5
x - 10 = 4
x = 4 +10
x = 14
Vậy x =14
