Answer»

ANSWER:

Simplifying

3Y + -15 = 39

Reorder the terms:

-15 + 3y = 39

Solving

-15 + 3y = 39

Solving for variable 'y'.

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

Add '15' to each side of the equation.

-15 + 15 + 3y = 39 + 15

Combine like terms: -15 + 15 = 0

0 + 3y = 39 + 15

3y = 39 + 15

Combine like terms: 39 + 15 = 54

3y = 54

Divide each side by '3'.

y = 18

Simplifying

y = 18
