1.\(y\times3,6+y\div0,25=152\)
\(y\times3,6+y\div\frac{1}{4}=152\)
\(y\times3,6+y\times4=152\)
\(y\times\left(3,6+4\right)=152\)
\(y\times7,6=152\)
\(y=152\div7,6\)
\(y=20\)
2.\(\left(22,54-y\right)+4,5=15,7\)
\(22,54-y=15,7-4,5\)
\(22,54-y=11,2\)
\(y=22,54-11,2\)
\(y=11,34\)
3. 24,5 + 1,2 : 6 - 3,12 = 24,5 + 0,2 - 3,12 = 24,7 - 3,12 = 21,58

a) 9,72 - 3,2 -x = 1,8+0,5
6,52-x=2,3
x=6,52 - 2,3
x = 4,22
b) x:5 +4,5 = 15,7 x 0,5
x:5 +4,5 = 7,85
x:5 = 7,85-4,5
x:5=3,35
x = 3,35 x 5
x = 16,75

x-15,7-2,18=36,5
=>x-(15,7+2,18)=36,5
=>x-17,88=36,5
=>x=36,5-17,88
=>x=18,62
Vậy x=18,62

\(a,x-14,03=15,94\) \(b,x+15,7=60,8\)
\(x=15,94+14,03\) \(x=60,8-15,7\)
\(x=29,97\) \(x=45,1\)

Ta có:
x − 4 , 5 = 7 , 98 x = 7 , 98 + 4 , 5 x = 12 , 48
Vậy x = 12 , 48
Đáp án D
![](https://rs.olm.vn/images/avt/0.png?1311)
`x-15,7=4,5`
`=> x=4,5 + 15,7`
`=>x= 20,2`
vậy `x=20,2`
