    3x+y=27, when x=7

    1. Replace any x in the equation with 7.

    3 (7) + y=27

    2. Simplify.

    21+y=27

    3. Solve for y.

    y=27-21

    y=6

    4. Check your answer by inserting x=7 and y=6 into the original equation.

    3 (7) + 6=27

    21+6=27

    27=27

    Yes, it checks.
