Hope it helps

Answer 2

b) 3x + 5 = 11

Step-by-step explanation:

Q.

Identify the linear equations from the given expressions.

a) x² + x = 2

b) 3x + 5 = 11

c) 5 + 7 = 12

Solution -

a) x² + x = 2

Here degree (highest power) of polynomial is 2, so it is not a linear equation. It is a quadratic equation.

b) 3x + 5 = 11

Here degree of polynomial is 1 so it's a linear equation.

c) 5 + 7 = 12

It is not a equation, because there isn't any variable.

So answer is option b)
