Solve for y: 5y - 7 = 3.

To solve the equation ( 5y - 7 = 3 ), the first step is to isolate the term with ( y ). You begin by adding 7 to both sides of the equation, which gives you ( 5y = 10 ).

Next, to solve for ( y ), you divide both sides of the equation by 5. This results in ( y = 2 ).

This calculation shows that the correct answer is indeed 2, as it satisfies the original equation when substituted back in. When substituting ( y = 2 ) back into the equation, you get ( 5(2) - 7 = 3 ), which simplifies to ( 10 - 7 = 3 ), confirming that both sides are equal. Thus, the solution ( y = 2 ) is validated.
