Which property of addition is shown by the equation 6 (y+7) = 6y+7

None

Step-by-step explanation:

Not only is this multiplication, it is incorrect.

(y + - 7) (y + 6) = 0

Reorder the terms:

(-7 + y) (y + 6) = 0

Reorder the terms:

(-7 + y) (6 + y) = 0

Multiply (-7 + y) * (6 + y)

(-7 (6 + y) + y (6 + y)) = 0

((6 * - 7 + y * - 7) + y (6 + y)) = 0

((-42 + - 7y) + y (6 + y)) = 0

(-42 + - 7y + (6 * y + y * y)) = 0

(-42 + - 7y + (6y + y2)) = 0

Combine like terms: - 7y + 6y = - 1y

(-42 + - 1y + y2) = 0

Solving

-42 + - 1y + y2 = 0

Solving for variable 'y'.

Factor a trinomial.

(-6 + - 1y) (7 + - 1y) = 0

Subproblem 1

Set the factor ' (-6 + - 1y) ' equal to zero and attempt to solve:

Simplifying

-6 + - 1y = 0

Solving

-6 + - 1y = 0
