Answer:


  • \boxed{\sf{y=-(-2x+6)/(3) }}

Explanation:

Given:

  • Isolate the term of x and y from one side of the equation.

To find:

  • The value of y.

Solutions:

-3y+1=7-2x

First, you have to subtract by 1 from both sides.


\Longrightarrow: \sf{-3y+1-1=7-2x-1}

Solve.


\Longrightarrow: \sf{-3y=-2x+6}

Then, you divide by -3 from both sides.


\Longrightarrow: \sf{(-3y)/(-3)=-(2x)/(-3)+(6)/(-3)}

Solve.

Divide these numbers from left to right.


\Longrightarrow: \sf{-(2x)/(-3)+(6)/(-3)}


\Longrightarrow: \sf{(-2x+6)/(-3)}


\Longrightarrow: \sf{=-(-2x+6)/(3)}


\Longrightarrow: \boxed{\sf{y=-(-2x+6)/(3)}}


\text{Therefore, the correct answer is {y=-$(-2x+6)/(3)$}}}}.

I hope this helps, let me know if you have any questions.
