Question

nhờ mọi người trả lời cụ thể đc ko ạ .

1 tìm x biết

3 - 2 . ( x +1) = 51

Answer 1

Ta có: \(3-2\left(x+1\right)=51\)

\(\Rightarrow2\left(x+1\right)=3-51\)

\(\Rightarrow2\left(x+1\right)=-48\)

\(\Rightarrow x+1=-48:2\)

\(\Rightarrow x+1=-24\)

\(\Rightarrow x=-24-1\)

\(\Rightarrow x=-25\)

Vậy \(x=-25.\)

Answer 2

\(3-2.\left(x+1\right)=51\)

\(2.\left(x+1\right)=3-51\)

\(2.\left(x+1\right)=-48\)

\(x+1=-48:2\)

\(x+1=-24\)

\(x=-24+1\)

\(x=-23\)

Answer 3

Hoàng Thị Ngọc Anh đúng r đó :)

Answer 4

3-2(x+1)=51

\(\Rightarrow\)2(x+1)=3-51

\(\Rightarrow\)2(x+1)-48

\(\Rightarrow\)x+1=-48:2

\(\Rightarrow\)x+1=-24

\(\Rightarrow\)-24-1

\(\Rightarrow\)-25

Answer 5

\(3-2\left(x+1\right)=51\)

\(\Rightarrow2\left(x+1\right)=-48\)

\(\Rightarrow x+1=-24\)

\(\Rightarrow x=-25\)
