Question

7) Identify the algebraic linear equations from the given expressions.
(a) x2 + x = 2
(b) 3x + 5 = 11

(C) 5 + 7 = 12​

Answer 1

Step-by-step explanation:

An algebraic linear equation is the one in which each term has an exponent of 1 and graphically it can be represented in a straight line.

From above there is only one equation which represent and straight line. i.e ( 3x + 5 = 11 )

The above two not from a linear line and option c is not equation.

Answer 2

Identify the algebraic linear equations from the given expressions.

(a) x2 + x = 2

(b) 3x + 5 = 11                

(c) 5 + 7 = 12

(d) x + y2 = 3

Solution:

(a) x2 + x = 2 is not a linear equation.

(b) 3x + 5 = 11 is a linear equation.

(c) 5 + 7 = 12 is not a linear equation as it does not contain variable.

(d) x + y2 = 3 is not a linear equation.
