Question

The degree of the equation $7x^2-6xyz-3=9x$ is

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

The degree of a term is the sum of the exponents of the variables that appear in the term. The degree of an equation is the highest degree among its terms.

For each term in the given expression, we can observe the degree as follows:

Term	Sum of exponents
$7x^2$	$2$
$-6xyz$	$3$
$-3$	$0$
$9x$	1

As the highest sum of exponents of variable(s) in a term of the equation is 3.

Hence, the degree of the equation is 3.
