Which of the following are algebraic equations?
i. 3.1x−11.2=2.5x+2.3
ii. +=
iii. 1/2+1/2=2/4

The equation (i) is the only algebraic equations.

Step-by-step explanation:

From the given examples of equations the equation (i) is the only algebraic equations.

(i) 3.1x - 11.2 = 2.5x + 2.3.

This is an example of algebraic equation with single variable x.

(ii) + = 2

This could be an equation with variable but both the sides being equal they cancel each other and no equation remains.

(iii) 1/2 +1/2 = 2/4

This is not an algebraic equation since there is no variable. (Answer)
