3y + 2x + xy + 12 = 0 IS an equation!
Because it has ONE equal sign with numeric expressions on the left and right.
A) How many different unlike terms are there in this equation?
A term is a series of factors multiplied together. A term is "like" another if they have identical variable factors.
The given equation's terms are all different, except if you subtract 12 from both sides then the 0 and 12 on the right would be like terms.
So there are 4 unlike terms in the equation: 3y, 2x, xy, and 12.
B) What is the like terms that could be combined with 0 if it was moved mathematically correctly to the right side of the equation?
12
C) What is the coefficient of y? 3; because a coefficient is the number multiplying variables.
D) What is the coefficent of xy? 1; even though it is not usually shown.
