Em chia nhỏ từng phần để mọi người hỗ trợ sớm nhất nhé !!

Bạn cần viết đề bài bằng công thức toán để được hỗ trợ tốt hơn. 

x^2+2x-3/3+2x/4=x^2/3

Bài dài quá, lần sau chia nhỏ câu hỏi nhé!!!!!

đúng vậy

\(\dfrac{x}{y}=\dfrac{6}{5}\)⇒\(\dfrac{x}{6}=\dfrac{y}{5}\)

Áp dụng tính chất dãy tỉ số bằng nhau ta có:

\(\dfrac{x}{6}=\dfrac{y}{5}=\dfrac{x+y}{6+5}=\dfrac{121}{11}=11\)

⇒\(x=66;y=55\)

các bạn giải rõ giúp mik nha! rùi mik tik cho, :3

Chia nhỏ ra ik ạ

\(\left(2x+3\right)\left(2x-3\right)-4x\left(x+5\right)=4x^2-9-4x^2-20x=-20x-9\)

\(5x\left(x-3\right)+\left(x-2\right)^2=5x^2-15x+x^2-4x+4=6x^2-19x+4\)

\(x\left(x+2\right)-\left(x-3\right)\left(x+3\right)=x^2+2x-\left(x^2-9\right)=x^2+2x-x^2+9=2x+9\)

 3/10 x x=2/5 

x = 2/5:3/10

x = 4/3

1/8 : x  = 1/2 

x = 1/8:1/2

x= 1/4

5/6 : 3/4  = 5/6x4/2= 10/9

1: 2/3= 1/1 x 3/2= 3/2

5/6 + 3/4  = 19/12

1 + 2/3= 1/1+2/3= 5/3

 5/6 - 3/4 = 1/12

1 - 2/3= 1/1-2/3= 1/3

5/6 x 3/4= 5/8

1/1x2/3= 2/3

1/8:x=1/2

1: (x+1)(y+2)=5

mà y+2>=2(do y là số tự nhiên)

nên (x+1;y+2)∈(1;5)

=>(x;y)∈(0;3)

2: (x+1)(y+2)=6

mà x+1>=1 và y+2>=2(do x,y là các số tự nhiên)

nên (x+1;y+2)∈{(3;2);(2;3);(1;6)}

=>(x;y)∈{(2;0);(1;1);(0;4)}

3: (x+2)(y+3)=6

mà x+2>=2 và y+3>=3(do x,y là các số tự nhiên)

nên (x+2;y+3)∈{(2;3)}

=>(x;y)∈(0;0)

4: (x-1)(y+3)=6

mà y+3>=3(do y là số tự nhiên)

nên (x-1;y+3)∈{(2;3);(1;6)}

=>(x;y)∈{(3;0);(2;3)}

5: (x-1)(y-3)=5

=>(x-1;y-3)∈{(1;5);(5;1)}

=>(x;y)∈{(4;8);(6;4)}

6: (x-2)(y-1)=3

=>(x-2;y-1)∈{(1;3);(3;1)}

=>(x;y)∈{(3;4);(5;2)}

7: (x-2)(y-1)=5

=>(x-2;y-1)∈{(1;5);(5;1)}

=>(x;y)∈{(3;6);(7;2)}

8: (x-3)(y+1)=7

mà y+1>=1(do y là số tự nhiên)

nên (x-3;y+1)∈{(1;7);(7;1)}

=>(x;y)∈{(4;6);(10;0)}
