Assuming we want to factor the formula to (x+3)(x+3), you want to have a +9 where there is a -4 now. So you must add 13.

What is the value of y if (4y + 8) - (7y - 12) = 11? (PLEASE ANSWER + 10 POINTS!!!!)?
lyudmila [28]
Hello!

(4y + 8) - (7y - 12) = 11     is     1(4y + 8) - 1(7y - 12) = 11

1(4y + 8) - 1(7y - 12) = 11               Given
        4y + 8 - 7y + 12 = 11              Distribute the 1 and the -1
                    -3y + 20 = 11             Combine like terms
                            -3y = -9              Subtract 20 from both sides
                               y = 3                Divide both sides by -3

Answer:
y = 3
