An equation is formed of two equal expressions. There exists only one solution to the problem which is equal to 27. Thus, the correct option is A.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation can be found as shown below,
4(x-5)=3x+7
4x - 20 = 3x + 7
4x - 3x = 20 + 7
x = 27
Hence, there exists only one solution to the problem which is equal to 27. Thus, the correct option is A.
