y x 0,3 + y x 0,2 + y x 0 , 5 = 3570
y x ( 0,3 + 0,2 + 0,5 ) = 3570
y x 1 = 3570
y = 3570 : 1
y = 3570
Vậy y = 3570

3,75 \(\times\) y - y \(\times\) 3,74 = 3,5 \(\times\) 0,5
y \(\times\) ( 3,75 - 3,74) = 1,75
y \(\times\) 0,01 = 1,75
y = 1,75 : 0,01
y = 175

38 x y + y + y = 25 x 8
38 x y + ( y x 1 ) + ( y x 1 ) = 2000
y x 38 + 1 + 1 = 2000
y x 40 = 2000
=> y = 2000 : 40
y = 50

y . 5 + y : 0,25 = 22,5
y.5 + y . 4 =22,5
y.(5+4)=22,5
y.9 =22,5
y=22,5 : 9
y = 2.5
Kick nha^^

y x 7,26 + y x 3,74 - y = 2019
y x ( 7,26 + 3,74 - 1 ) = 2019
y x 10 = 2019
y = 2019 : 10
y = 201,9
