Ai mik mik lại
(x-34).15=0
đáp án =0
(18-x).26=0
đáp án =0
đúng k nha
( x - 34 ) . 15 = 0 ( 18 - x ) . 26 = 0
x - 34 = 0 : 15 18 - x = 0 : 26
x - 34 = 0 18 - x = 0
x = 0 + 34 x = 18 - 0
x = 34 x = 0
a ) ( x - 34 ).15 = 0
x - 34 = 0.15
x - 34 = 0
x = 0 + 34
x = 34
b) ( 18 - x ) . 26 = 0
18 - x = 0.26
18 - x = 0
x = 18 - 0
x = 18
k mình nhé
