Answer:x=-1


add 1 to 3 to get 4, add 3 to -7 to get -4, divide both sides by -4

Answer:

  • -1


\:

Explanation:

Given Equation,


\\ {\longrightarrow \qquad{ \sf{-3x+3=-7x-1}}}\\ \\

Adding 7x to both sides we get,


{\longrightarrow \qquad{ \sf{-3x+3 + 7x=-7x-1 + 7x}}}\\ \\


{\longrightarrow \qquad{ \sf{4x+3=-1}}}\\ \\

Subracting -3 from sides we get,


\\ {\longrightarrow \qquad{ \sf{4x+3 - 3=-1 - 3}}}\\ \\


{\longrightarrow \qquad{ \sf{4x=-4}}}\\ \\

Dividing both sides by 4 we get,


\\ {\longrightarrow \qquad{ \sf{ (4x)/(4) = ( - 4)/(4) }}}\\ \\


{\longrightarrow \qquad{ \sf{x=-1}}}\\ \\
