b) y - 45600 = (2019 - 419) x 4 x 25
a) (y + 5) x 2020 = 205 x 2020
(y + 5) x 2020 = 414100
y + 5 = 414100 : 2020 = 205
y = 205 - 5 = 200
a) y= 200

Tìm x:
a) x x 3 = 8,4;
b) 5 x x = 0,25.
a) x x 3 = 8,4
x = 8,4 : 3

b) 5 x x = 0,25
x = 0,25 : 5
x = 0,05
Tìm x:
a) x x 3 = 8,4;

b) 5 x x = 0,25.
x=0,25:5
x=0,05
a, X x 3 = 8,4
=> X = 2,8
b , 5 x X = 0, 25
=> X = 0,5
Tìm y:
a) y x 2,8 + 5,2 x y = 48
b) y x 12,25 – y + y x 2,75 = 1050
\(a,y\times2,8+5,2\times y=48\\ y\times\left(2,8+5,2\right)=48\\ y\times8=48\\ y=\dfrac{48}{8}=6\\ ---\\ b,y\times12,25-y+y\times2,75=1050\\ y\times\left(12,25-1+2,75\right)=1050\\ y\times14=1050\\ y=\dfrac{1050}{14}=75\)
a: \(y\cdot2,8+y\cdot5,2=48\)
=>\(y\left(2,8+5,2\right)=48\)
=>\(8y=48\)
=>\(y=\dfrac{48}{8}=6\)
b: \(y\cdot12,25-y+y\cdot2,75=1050\)
=>\(y\left(12,25-1+2,75\right)=1050\)

Học tốt
x×3=8,4
x=8,4:3
x=2,8
vậy x=2,8
5×x=0,25
x=0,25:5
x=0,05
0,16:x=2-0,4
0,16:x=1,6
x=0,16:1,6
x=0,1
vậy x=0,1
