Answer:

  • -1

[tex] \: [/tex]

Step-by-step explanation:

Given Equation,

[tex] \\ {\longrightarrow \qquad{ \sf{-3x+3=-7x-1}}}\\ \\ [/tex]

Adding 7x to both sides we get,

[tex]{\longrightarrow \qquad{ \sf{-3x+3 + 7x=-7x-1 + 7x}}}\\ \\ [/tex]

[tex]{\longrightarrow \qquad{ \sf{4x+3=-1}}}\\ \\ [/tex]

Subracting -3 from sides we get,

[tex] \\ {\longrightarrow \qquad{ \sf{4x+3 - 3=-1 - 3}}}\\ \\ [/tex]

[tex]{\longrightarrow \qquad{ \sf{4x=-4}}}\\ \\ [/tex]

Dividing both sides by 4 we get,

[tex] \\ {\longrightarrow \qquad{ \sf{ \frac{4x}{4} = \frac{ - 4}{4} }}}\\ \\ [/tex]

[tex]{\longrightarrow \qquad{ \sf{x=-1}}}\\ \\ [/tex]
