3y+2x+xy+12=0 Is this an equation

Question

A) How many different unlike terms are there in this equation?

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?

C) What is the coefficient of y?

D) What is the coefficent of xy?

 

Answer 1

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.
