(7y+3) (3y-5) (9y+7 )
whats is the value of y?

Simplifying

7y + 3 + 3y + -5 = 9y + 7

Reorder the terms:

3 + -5 + 7y + 3y = 9y + 7

Combine like terms: 3 + -5 = -2

-2 + 7y + 3y = 9y + 7

Combine like terms: 7y + 3y = 10y

-2 + 10y = 9y + 7

Reorder the terms:

-2 + 10y = 7 + 9y

Solving

-2 + 10y = 7 + 9y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-9y' to each side of the equation.

-2 + 10y + -9y = 7 + 9y + -9y

Combine like terms: 10y + -9y = 1y

-2 + 1y = 7 + 9y + -9y

Combine like terms: 9y + -9y = 0

-2 + 1y = 7 + 0

-2 + 1y = 7

Add '2' to each side of the equation.

-2 + 2 + 1y = 7 + 2

Combine like terms: -2 + 2 = 0

0 + 1y = 7 + 2

1y = 7 + 2

Combine like terms: 7 + 2 = 9

1y = 9

Divide each side by '1'.

y = 9

Simplifying

y = 9
