Answer:

the value of m for which the pair of simultaneous equations has indefinitely many solutions is m = 1.

Step-by-step explanation:

To find the value of m for which the pair of simultaneous equations 3x + my = 5 and (m + 2)x + 5y = m has indefinitely many solutions, we need to determine the condition that allows for infinitely many solutions.

The pair of simultaneous equations can be written as:

3x + my = 5 (Equation 1)

(m + 2)x + 5y = m (Equation 2)

To have infinitely many solutions, the two equations must represent the same line. This occurs when the coefficients of x and y in the two equations are proportional.

Let's equate the coefficients of x and y from the two equations:

From Equation 1: coefficient of x = 3

From Equation 2: coefficient of x = m + 2

Therefore, we have the equation: 3 = m + 2

Solving this equation for m, we subtract 2 from both sides:

m + 2 - 2 = 3 - 2

m = 1

So, the value of m for which the pair of simultaneous equations has indefinitely many solutions is m = 1.
