Question

Which of the following is an algebraic equation?

• A. 1+1=2
• B. $x>5$
• C. $x+3=7$
• D. $5>7$

Answer 1

The correct option is C

$x+3=7$

1 + 1 = 2 is an equation. But it is not an algebraic equation since neither of the expressions has a variable in them.
$x>5$ is not an equation since the quantities $x$ and 5 are not equal.
$x+3=7$ is an algebraic equation since the quantities $x+3$ and 7 are equal, and the expression on the left-hand side has a variable.
$5>7$ is not an equation since the quantities 7 and 5 are not equal
