11.(y+3)=5.y+105
=>11.y+3=5.y+105
=>(11.y).(5.y)=105-3
=>(11.5)y=102
55y=102
y=102/55
b) 11.(y-6)=(4.y)+11
=>11y-6=4y+11
=>44y=11+6
44y=17
y=17/44

Y x 6 + 11 x 5/11 = 2025
3450 - y = 6440 : 32
y x 1/3 + y x 2/5 = 11/15
.6 km2 10 m2 = … m2
11.Tính: 5 x 4/5 = ...
12.Tìm y biết: y + 1/2 = 4/5
Vậy y = ...
1. Tìm Y :
a) ( 9407 - 7274 ) : Y = 8058 : 34
b) Y x 128 - Y x 17 - Y x 11 = 576000
2. Tính bằng cách nhanh nhất :
a) ( 125 x 36 ) : ( 5 x 9 )
b) 1/10 + 2/10 + 3/10 + 4/10 + 5/10 + 6/10 + 7/10 + 9/10
TÌM Y
1/5 + 8/15 : y = 1/2
4/11 x y - 6/11 = 2/5
LƯU Ý : 1/5 = 1 phần 5 tương tự các câu khác
tìm y
a) y : 4/11 x 3/5 = 27/4
b) y + 7/2 - 5/9 = 14/3
y x \(\dfrac{11}{12}\) + y x \(\dfrac{3}{4}\) = \(\dfrac{10}{11}\)
y : 33 = 9/66 4/5 x y = 10/11 : 3/4
4/11 x y - 6/11 =2/5
