Answer:

Option (c) is correct.

The given equation 11x + 25 = 7x + 15 has one solution.

Explanation:

Given : Equation 11x + 25 = 7x + 15

We have to find the number of solution for the given equation

11x + 25 = 7x + 15

Consider the given equation 11x + 25 = 7x + 15

Subtracting 7x both side, we get,

11x + 25 -7x = 7x + 15 -7x

Simplify, we have,

4x + 25 = 15

Subtract 25 both side, we get,

4x + 25 - 25 = 15 - 25

Simplify, we get,

4x = - 10

Divide both side by 4, we get,


x=(-10)/(4)=(-5)/(2)

Thus, The given equation 11x + 25 = 7x + 15 has one solution.
