Question

Which of the following can be considered as an algebraic equation?

• A. 5 + 67 = 80 - 8
• B. 2x + 77 > 3
• C. $3x+4y\le 8$
• D. $3x^2+7y+3=0$
  

Answer 1

The correct option is D $3x^2+7y+3=0$


An equation is a statement of an equality containing one or more variables.
5 + 67 = 80 - 8 does not have a variable.
$2x+77>3$ and $2x+77>3$ and $3x+4y\le 8$ are inequalities. $3x+4y\le 8$ are inequalities.
Only $3x^2+7y+3=0$ is an equation.
