[x0x0x] là sao

10101

không có bằng mấy à

x0x0x : X x 3 – 20202

= 10101 x 3 – 20202

= 30303 – 20202

= 10101

Đáp số:x=9

  x0x0x : X x 3 - 20202

= 10101 x 3 - 20202

= 30303 - 20202

= 10101

Chúc bạn học giỏi

1)= 111111xa : (ax37)- 4866:6

=111111xa: 37xa- 811

= 3003-811= 2192

2)

= 10101x X :X x3 - 20202

= 30303-20202=10101

Bài 4: Tìm x

a. \(\left(2x-5\right)+17=6\)

\(2x-5=6-17\)

\(2x-5=-11\)

\(2x=-11+5\)

\(2x=-6\)

\(x=-3\)

b.\(10-2\left(4-3x\right)=-4\)

\(-2\left(4-3x\right)=-4-10\)

\(-8+6x=-14\)

\(6x=-6\)

\(x=-1\)

c. \(-12+3\left(-x+7\right)=-18\)

\(3\left(-x+7\right)=-18+12\)

\(-3x+21=-6\)

\(-3x=-27\)

\(x=9\)

d.\(24:\left(3x-2\right)=-3\)

\(24:\left(-3\right)=3x-2\)

\(-8=3x-2\)

\(-6=3x\)

\(x=-2\)

\(\left(x+\dfrac{1}{3}\right)\times\dfrac{9}{14}\times\dfrac{7}{3}-\dfrac{1}{3}=1:\dfrac{9}{5}\\ \Rightarrow\left(x+\dfrac{1}{3}\right)\times\dfrac{3}{2}-\dfrac{1}{3}=\dfrac{5}{9}\\ \Rightarrow\left(x+\dfrac{1}{3}\right)\times\dfrac{3}{2}=\dfrac{5}{9}+\dfrac{1}{3}\\ \Rightarrow\left(x+\dfrac{1}{3}\right)\times\dfrac{3}{2}=\dfrac{8}{9}\\ \Rightarrow x+\dfrac{1}{3}=\dfrac{8}{9}:\dfrac{3}{2}\\ \Rightarrow x+\dfrac{1}{3}=\dfrac{16}{27}\\ \Rightarrow x=\dfrac{16}{27}-\dfrac{1}{3}\\ \Rightarrow x=\dfrac{7}{27}\)

tại đề sai nên không làm được

uk, mình không bik nữa mà bạn lam2dc khong

=2x³ + x² - 2x² - x + 6x + 3

=x²(2x+1)-x(2x+1)+3(2x+1)

=(2x+1)(x²-x+3)
