3(5 - y) = 3(y + 4)

15 - 3y = 3y + 12

-3y - 3y = 12 - 15

-6y = -3

y = -3/-6

y = 1/2

3(5 - 1/2) = 3(1/2 + 4)

3(9/2) = 3(9/2)

27/2 = 27/2 TRUE

15 - 3y = 3y + 12

-3y - 3y = 12 - 15

-6y = -3

y = -3/-6

y = 1/2

3(5 - 1/2) = 3(1/2 + 4)

3(9/2) = 3(9/2)

27/2 = 27/2 TRUE

3(5 - y) = 3(y + 4)

(3)(5)+(3)(- y)=(3)(y)+(3)(4)

15 + -3y = 3y + 12

-3y + 15 = 3y + 12

-3y + 15 = +12 -3y

-6y + 15 =12

-6y = 12 - 15

-6y = -3

y = -3 / -6

y = 1/2

(3)(5)+(3)(- y)=(3)(y)+(3)(4)

15 + -3y = 3y + 12

-3y + 15 = 3y + 12

-3y + 15 = +12 -3y

-6y + 15 =12

-6y = 12 - 15

-6y = -3

y = -3 / -6

y = 1/2
